2D Platformer Shoot-Em Up with different weapons and modifier the player can pick up. Killing enemies collects coins that can be spent in a shop at certain wave intervals. Every few waves the difficulty will increase, spawning more enemies. Upgrades can be picked up that unlocks abilities or adds to the player stats.

Player has a health bar and an energy bar
Player can buy different weapons, each with their own ammo count. Energy can be spent to fire if the weapon is out of ammo.
Modifiers to weapons apply to the currently equipped weapon.

Right now everything is overtuned to make the demo quicker to play.

Executable:
IMPORTANT: Restart the game once through the pause menu (Esc/Select) to fix the bugged UI in the WebGL version.

A WebGL version exists on Itch.io, I would recommend using the desktop version if you want to use controller and get better performance (no object pooling, so WebGL sometimes lag when killing enemies). The UI is also horribly unscaled for web so it's a bit buggy.

Health regeneration

Pretty much any variable for the player can be modified by pickups that spawn after each wave.
