Interesting game. While playing with my friend we found that the game does not feel great. Some characters feel OP, and what others do is not even obvious. The fact that a single player can easily use all the pickups in quick succession means the other player can be in a disadvantage. Also we found main menu and pause menus to be inconvenient where we would accidentally open pause and would not figure out how to resume.
We also found a major bug in one of the levels. It seems that some objects can cause the players to float, when floating the players can't do anything to each other.
