The difficulty is a little high for me, but the concept is really great! It's interesting to see myself instinctively try to dodge the walls by shrinking when I actually need to switch.
I did not manage to complete the game due to the difficulty. I think that the speed of the player needs to be slower and the level made easier at the start of the game. There's also a bit of a problem distinguishing walls from the background because they are using similar color.
Great job on the jam! You might want to get on to GMTK's discord sever and get help from the mod there to replace your game file.
