So sorry it didn't work again :/ Thanks for your patience and for keeping to try it. I'm trying my best to fix it and have increased the detection area for the pieces, but there's still a chance the issues will occur. :(
I was able to complete it! According to the LD rules you're allowed to update your original build with bug fixes, so I don't think it would be unreasonable to backport this fix to your non-post-jam build.
