Hi, I just had fun playing this very inventive game! The keybinding issue has already been adressed for this V2, but I also noticed an error where, at least during the game over screen with the overfed Happ, I can still click on the right side of the screen and I'll hear the jiggling effects when you click on Happ's body during gameplay mode.
I don't think I'd have anything else to report bugs-wise, but I need to say that the drag'n'drop minigame is nearly impossible to beat on the higher speed, unless I also configure my mouse at a faster speed. Maybe you're forced to fail at it if it's related to Happ's anxiety increasing, but I'd like to believe a flawless run is possible.
Wishing you the best for completing this game, and I'm glad the kickstarter is almost at 100%!
