Fun
Not enjoyable. A platformer but with nothing innovative and plagued with bugs.
Aesthetics
Very nice pixel art. Looks professional. No complaints.
Music
It is a bit of a low tempo, creepy score. The music itself is good, but it is a bit of a stretch to say it matches the cuter art style, even if the tiles are in a dungeon.
Sound
Outside of the background music, I didn't hear anything.
Mechanics
Bad. You can't see below you, and the game starts with you falling onto spikes you can't see. The movement speed is medium, and the jumping acceleration is very high, so even the movement clashes.
When you die, you get rocketed to the right. I thought this might be some sort of gravity puzzle mechanic, but it turns out it is just a bug. That's a shame. A gravity puzzle with death would have been very cool.
Often you aren't sure if you are touching the hitbox of hazards such as saws.
Story
None as far as I am aware
Theme
Doesn't try to do anything with death. This is just a platformer. Music and wall tiles clash with character sprite.
Good job on your first jam, but this feels more like you just wanted the free course.
