Feedback (INTERACTION)

Visual Feedback:

Menu Screen:

Interactions(buttons): Buttons should highlight if hovering and flicker if clicked.

Taking Damage: If the player is crushed by an insect, there should be an flatten animation.

Health and Stamina: Health information will be displayed with a health bar.

Low Stats: If the player's health or stamina is lower than 60%, the bar should turn yellow, if it's lower than 30%, the bar should turn red.

The screen should also have a red vignette around the edges to convey the critical state to the player.

Eating Insects: If the player consumes an insect, there should be an animation followed as well as text displaying how much DNA was earned.

Purchasing Upgrades: If the player purchases upgrades, it should visually show how much currency has been removed from the player's total.

Audio Feedback

SFX:

Taking Damage: If the player is crushed by an insect, it should play a squish sound.

Eating Insects: If the player consumes an insect or their waste, it should play a crunching sound.

Collecting Currency: If the player collects currency, it should play a synthetic chime sound.

Purchasing Upgrades: If the player purchases upgrades for core stats, it should play a cash sound effect("Cha-Ching").

UI Interaction(button/menu): There should be pop or tap noise when interacting with buttons on the menu or upgrade.

Music: 

Menu Screen: Should be a mellow, melodic and lighthearted tune.
Gameplay Screen: Should be an erratic whimsical tune.

Death Screen: Should be lighthearted and motivating, since death isn't permanent.

Upgrades/Evolution Screen: 

• Upgrading should set the tone for decision-making and progression. A futuristic vibe, perhaps light synth. 

• Evolving should be more impactful and mysterious.
