Interesting concept!
But I have the same issue, the K is not working, neither is jumping in the paint bucket.
It is having a problem where it is necessary to press K several times to activate it, we are updating it and putting a visual indicator that shows when it was active to make it easier to identify it within the game. Thanks for the feed!
I mashed the K button. :)
I’ll try the new version once it’s up after the jam!
