Cool game! But I'd like to leave some comments to improve the player experience.
- The gunfire sounds are too loud
- Freezes and lag on the first shot (I played on Linux; after the first few shots everything smoothed out)
- It would be great if items were picked up automatically (ammo at the very least). Or even split items into categories: weapons, health packs, ammo.
- It would be nice to have an option to turn off the CRT-style scanlines — they get in the way in dark areas.
- The inventory system could use a fix: right now you can pick up an item when the inventory is already full, and the item just disappears.
- It would be absolutely perfect to add some feedback when enemies hit the player — at minimum, it'd be nice if the player's portrait reacted with a sprite animation, Doom-style or something along those lines, or if the Hit Points label got jolted somehow with a tween.
Other than that, the game is interesting and fun (the fire ability in particular is a blast to use), though a bit tough — you run out of ammo too fast. Good luck with development!
