Hey! I know it's a bad rating, but don't get down about it. I started programming years ago, and I remember making games like this too. I wanted to give you an honest rating and review.
Fun: I'm a big fan of action games, but the combat doesn't feel fun. There's no weight to your attacks, enemies don't have a health bar, and you can't tell if you're actually hitting an enemy or not. The first two levels are very straightforward, but the third one is, as far as I know, impossible to complete without glitches. I've gotten stuck in walls as well.
Aesthetics: The game looks bad, the tiles are good, they're just used incorrectly. The game also wildly changes from professional art, to amateur digital art, to stock images, to hand-drawn. It's really off-putting.
Music: You need to diversify the music, it would be fine in one level, but three wears it out.
Sound: There weren't any sound effects, which I understand, my game didn't have any either.
Mechanics: Moving, attacking, and killing works, it just doesn't feel good.
Story: It's generic, but it works, and it makes sense. It's easy to follow what's happening.
Theme: It makes sense, you die at the start of the game, but I feel like it could've been done better. A gameplay mechanic based on death would've helped the game out a lot.
