Overall: It's a well made game! I like how when you attack, you scoot over a little bit. It makes it more interesting than just having a static character.
Fun: I enjoy the snappy quick paced gameplay, and the difficulty increases at a very well made pace. I think the gameplay gets a bit stale quickly, so to make it more fun I challenged myself to see how far I could move the guy to the left. That definitely spiced it up! I was able to move far enough that the background repeated!
Innovation: I wish the game had a bit more to it. This jam alone, with a total of 20 games, I have played 2 other games similar to this one. "Generic Game" and "Nobody Grooves like Cadenska Voldmirovna" which both do more than just increase your score with a better combo. In "Generic Game" the score is also points for a shop, and buying things resets the combo making a risk/reward situation where you ponder if it's worth getting that upgrade or healing. In "Nobody Grooves like Cadenska Voldmirovna" the combo also makes your attacks stronger, helping out in the later stages of the game.
Theme: I like how the combo affects your score, but I personally think this is a lazy take on the theme. The score is essentially ((x^2)/2)+(x/2) where x is the number of killed goblins (unless you miss, but for some reason I initially assumed missing would kill me). In the grand scheme of things, why is that more significant than just making the score equal to the number of killed goblins? Especially considering that's the theme of the game. My final score was 2850, so I killed 75 goblins without missing. Going back to my comments on Innovation, I feel like the combo needs to have a more dramatic effect on the gameplay than just the score.
Graphics: Since you didn't draw the artwork, allow me to comment on the other aspects of the visuals. I'm not a fan of the fuzzy grain postprocessing. Additionally, the game over screen is somehow "over" the post processing. I'm also just not a fan of Chromatic Aberration.
Mood: I like the dungeon/crypt aesthetic. The music certainly is too cheerful though. it sounds like I'm vibing at a fair, not fighting for my life.
Audio: The goblin exploding sound effects is pretty great. I also like the music, though it's a bit "stock music" sounding.
Humor: Nonsensical violence is always fun. Also the tiny splat as the goblins explode is humorous.
Final Thoughts: I think the game is a bit short. There's definitely incentive to play it again with the high score, but I feel like there's just not enough content to make it last. That said, it's still fun, and I enjoyed goofing off by moving far to the left and avoiding the objective entirely by playing it in the very much not correct way.
