Thank you for the nice words and detailed feedback!
The two powerups you mentioned (chopsticks and teleport) are so confusing to use that it would practically take an essay to fully explain properly. We'll figure out a way of doing that eventually. The physics gets really weird when there's 2 sushi or in general interaction with enemies (Godot really hates ovals for some reason, we've made everything circular now and it should be better). We've fixed plenty of bugs and added a few improvements for the post jam release that will hopefully address the issues you've faced.
Thanks again!
