Nice game! I think it had a solid gameplay loop and pretty good atmosphere.
The art style and gameplay reminded of the ancient DOS game Heretic.
I quite liked the art and animations, though wish the game overall would've get more polish.
Feedback on issues encountered:
- Music resets when you switch between menu entries (look into autoloads/globals, with them you can loop music between scenes)
- "Back" button in level select doesn't work (missed connecting signal?), same as "main menu" button on death screen
- "How do I start the game?" problem mentioned by others
- On game start, if instead of pressing Enter you press A and then press Enter, the game stops responding
- I didn't understand what the 2nd weapon does. It makes a swing, but seemingly does no damage (enemies don't die) (on second thought, are there actually 2 types of enemies, immune to different types of weapon?)
- Sometimes I would get snagged on ramps and stop moving, which allowed enemies to catch and kill me (misaligned collisions?)
- If a group of enemies catches you, they can very quickly block your movement and/or insta-kill you (maybe make an invulnerability timer after getting hit, and/or make enemies pushable)
- Some enemies got stuck in the roof in one of the side rooms (I assume spawnpoints are misaligned?)
- Camera felt too sensitive, had to crank down mouse sensitivity to the minimum to make it playable; wish there was a setting for it
- When you die, you can't click the restart button with mouse (game keeps mouse cursor hidden and/or grabbed)
Hope that helps for your future projects.
