Very cool game!
This is obviously heavily inspired by RE4 and you did very well translating it's mechanics into 2D. I do have some suggestions if you plan to update this game though.
- Make the player faster: I know it's probably to build tension and terror, but it gets kinda annoying sometimes. It doesn't even need to be that much of a speed difference.
- Make the aim button hold and not toggle: I'm just used to the RE4 "hold down button to aim and release to stop aiming" thing. Just a nitpick
- Add more sound effects: I find it kinda odd how the player doesn't have a hurt sound effect. Maybe an entering door sound effect would be cool to?
- You can get softlocked in some bosses, such as the shadow plant thingy in the street section. I ran out of ammo and it wouldn't let me leave the building. Or I'm just that bad.
Yeah that's pretty much all my complains. The background music, though kinda repetitive builds up tension well. The enemy designs and mechanics are great, it doesn't just feel like your generic horror game where it walks towards you and shoot. They actually have some special "moves" (like chubs over there). Also I can't commend you enough for the spritework. Very, VERY excellent sprites.
Considering this game was made for a game jam, within the time limit I presume, is very impressive. Okay that was like one of the longest reviews I've written. Shows how much I like this game. I have a soft spot for gameboy and NES games.
