Programmer here - thank you for playing! I finally got a chance to look at the bug with the four abilities tonight, and it literally took me three minutes to fix... I'll upload a fixed build tomorrow, and keeping with the jam rules, I'll keep the original version of the build available for download.
One of the things I wish I'd had time to implement was better information on ability targeting rules. Something to prioritize for the Continue-It jam! The grid will also make it into the next iteration after the jam ratings are finished.
