Good work!
Some feedback:
- Good UI aesthetics and design
- Cute monster and characters
- I like how the audio helps indicate that there's something new in the room (ghosts) and lets me know to watch out for them.
- Camera can be a bit finicky when transitioning between two rooms (the ghost room and the room above it)
- Another keybind like press R to reset the level also. When I lose often, I don't like that I have to lift my hand off the keyboard to click Retry. It'd be nice to also press "R" to retry on that screen.
- Input feels a bit stiff? But doesn't hinder gameplay that much.
- I couldn't figure out how to get past the wall. There's apparently a button somewhere according to comments, but I couldn't find it. I think the game was a little too dark for me.
But I still had fun playing your game, good work :)
