Full vid (chapters below)

Game Start

Leaving the cylinder trigger spawns a Pinky (bull-like demon) at the top of each of the 4 stairs, simultaneously charging toward you!

The jumps in 2 of the torches can be seen. The foreground one leads to the secret area, the other one bounces you to it (just an extra way of spotting it)

Click below to jump to the relevant part(s) in the gameplay vid:

Secret Area from Jump in Torch

It sends player to the jump next to the rune on the wall, to then be sent to the launch pad destination

This above area was basically the green pillars, I built the rest to make it a player-traversible area

Demons can't traverse props (added floors etc) but I used floating demons along with normal ones in the pillar area

Top/Bottom Room (separated by a temporary floor)

The intent was to continue the red corridor have an upper section but iirc I couldn't get the Lost Soul (floating skull demon) to go that high

Would've been cool as the corridor is too narrow to strafe to avoid them!

The grey circle is the teleport when the player thinks they're dropping down to the ground, leading to the top of the minigame room in the video

The underground part (of the White Door Room)

Pic2: Secret I missed :P Switch hidden behind the fabric

By making the middle plank not-blocking, the secret behind remains obscured but accessible

The side plank is traversable and leads to the teleport that's not visible (I accidentally found the secret but took me a minute to get up the slope so both work as secrets!)

Next-To-Invisible Platform Room

Teleports player right under the edge of a ledge, so no immediate indication anything is above other than the yellow powerup in the corner of the roof

There's a teleport at the bottom that brings the player back to that platform (actually 3 ways, the line going downward from the Teleport To signaler is the one I'm referring to) 

Pic2: How the secret is revealed (yellow key) after the player finds that ledge & presses the switch

Inside of the In/Out Room 1

There's a door to enter, or the container above which has the teleport destination. The zombies only spawn after the latter is taken. So that when the player ends up here the 2nd way, it's the same room but with a development

SM doesn't let the outside part be directly accessed from the inside, it needs teleporting to. Also it can't have demons there :/ But other functions work, most of the minigames I made were in new rooms in this outside part

This room was to have 3 minigames, I didn't finish the shooting one as it was just generic compared to the other 2, & due to not being able to have even the floating monsters here, couldn't do my crystal-maze inspired demon going along the glass tube as a timer/fuse!

But by doing the one minigame properly, different things are revealed in this room, which eventually let you get a prize and leave. Still a complex room

& the game's a banger, it's what I expect dance dance revolution is like, jumping on things at the right time. In this case they have hazards under them set on a delay, so it's very quick-paced

Unfortunately similar to my Doom Minesweeper map things get triggered when they shouldn't sometimes, in this case leaving multiple options as the next one instead of only one.

Back in White Door Room

lol, I ended up triggering the secret by getting the BFG from behind that pillar (shouldn't be possible but it's probably already at the edge of the map grid so can't move it further in), but I was meant to shoot at that grated area to do so. Can be tough balancing secrets with spoonfeeding XD

Pic2 shows the blue key and the jump that's revealed later on in the gameplay. Key's in sight early on when I first entered but at that distance & fighting I didn't notice it

Bottom of Top/Bottom Room

This fkn room ruined some upcoming encounters as the upper section (pic2) kept infinitely spawning demons & there's a limit of 12 demons on the map at a time.

Cold Storage

The Borderlands-inspired weapon room. It was basically trading entries from the Player Loadout using reference functions. Didn't finish this one

Inside of In/Out Room 2

Accessed by the container above (door will disappear from the front of it during gameplay)

To make the most of the Mancubus (flamethrower demon) / turn it into a miniboss, the room has dynamic fire which activates when it takes damage (as mentioned some were prevented from spawning during gameplay)

I rarely do things for show alone, everything starts for a functional reason, then I may add to make it sit better with existing objects

I enter the area but since the demon didn't spawn just a quick vid of the area

The nefarious Invisible Platform Room. Spent forever here! (both making b4 & getting thru it the other day)

In the vid, when the green gas starts, is when a Cyber Mancubus (like the previous but green acid based instead of fire) spawns (spawner in pic2, bottom right. Connected above it is the On Killed signaler (the dagger object)

The demon that's visible as itself is the Revenant (jetpack demon) which would be fought in a glass cage - very tough!

If the demons spawned, the bull demons would chase you as you try to collect coins while avoiding obstacles

BFG Room (top of Sonic room stairs)

I couldn't get close enough to activate the switch in the gameplay, must be a placement issue. I remember spending a lot of time on that section, simply getting things to work when it's all so close together

If I had, the door to the next room would open, revealing a multi-stage process to get the BFG (Big Fkn Gun) on top of the rock column!

The Final Boss Room

The twist with mine is the Buff Stations, those areas with the grey cylinders, apply a buff to the demons that walk thru it

AI path points (green lines) ensure demons get to key places while they chase you etc

Pet Demon on your side

This room has a very Quake 3 feel, with the open parts in between you can fall through, & the clearer layout of the map as structures are free-standing

The Minigame Room seen from the outside (made in the Outside part of In/Out R2). The Archville (!) mini boss I made (in the leaning black column above the room) is the last entry in the blog

Below's a quick clip of the area

The Container Room. Doesn't photograph well. Very hidden way to enter, I only found it the 2nd time I was there (see vid)

It's containers pushed together in certain ways to make paths thru & around them. Quite a few secrets here, like false walls that can be walked through

Jumped around for ages trying to get thru this room, never saw the chainsaw :P

If I made it to the end of the yellow path in the Outside of In/Out R1. The nearby switch is hard to see in gameplay. That opens the door & inside if the player can climb these 2D (1px thick) classic objects to the last one, they teleport to the boss room

Ignore the text that comes up in the vid in this part, I misremembered :P

Archville!
