I've updated Creepy Crawlies on both Mac and PC to V1.01 to fix a few minor issues.
https://xerra.itch.io/creepy-crawliesChanges V1.01 - PC and Mac versions
===================================
Modified the collision window on the hornBug to make it a bit easier to deal with.
Grid drawing bug that could randomly occur solved.
Full screen now works correctly on the Numpad_0 and the F key.
Changed the identifying name to prevent potential conflicts with other apps as syntax was incorrect.
