Thanks for playing.
I was able to reproduce the bug. I think it has to do with UI focusing when the buttons are clicked. After I used a gourd by clicking on the icon, the focus would change to different buttons whenever I moved the arrow keys, and I would begin throwing gourds with the space key. I put the buttons in and never really tested them because I was using the hotkeys (1, 2, 3, 4 according to the order of icons; or p, b, c, r according to the first letter of each gourd; r is for red pepper because p was for pumpkin pie). I think I fixed the bug on my local development version by removing focus after a button is pressed. Is it okay if I update my submission with this bug fix while the voting stage is still going?
But, despite the bug, did you manage to put the gourds to good use ;) ?
How should I change the credits?
