I don't know what is worse: Live as a dead fish with some rice or get eaten by someone. It's a great question to solve while dodging chopsticks and other questionable flatware.
Back to the main topic, I think you should really think about upgrades. I like how Player must chose which set of upgrades they want each time they play because it promotes experimentation but unfortunately there is only one viable skill which is dash. The other starter upgrade, the jumping ability, is completely useless and when I tried it I quickly came back to dash. Horizontal movement is the king in your game and maybe adding some horizontal threats like a fan or something to push Sushi into danger can help balance the game.
I got really annoyed when I had to escape in the last second and let the XP orb just to come back and start over again. This decision should be changed to maybe Player need to stay only half of the original time to collect the XP.
I still don't know what is worse and I can't stop thinking about it. Thanks, you ruined my day. Good job!
