Well the ability to swap move speed with items is the most enjoyable and a concept that you can really build on. The least enjoyable was the slow movement speed of the player. I understand its part of the mechanic. But maybe instead of transferring the speed to the player, it transfers to the gun or something else, that way the player can still move at a normal speed.
I would appreciate some feedback on my GBJAM game. Thanks!
