Theme Implementation: 3/5. I do see a time mechanic, and it does feel "broken" I guess? But the idea doesn't stand out to me (admittedly, I used a similar idea for my game). I'll be very impressed if I find a game on this jam that implements this theme in an interesting way :)
Special Object: 2/5. I see a microphone on the main menu... That's about it. I won't give one star, because from what I understand, the game is kind of themed around it (I haven't watched jojo sorry!)
Fun Factor: 2/5. It gets old very quickly... There is a little bit of fun in trying to get as far as possible, but the player is not rewarded well enough for making progress, I think
Gameplay: 2/5. Not much gameplay. The turtle and the human give score, the weapons damage you, and the clock speeds you up. That is all.
Audio: 1/5. No audio (?)
Visuals: 2/5. The pixel art is not that bad, but overall the game feels low quality.
I'll remember this game for the funny jojo reference. Congratulations for the game!!
