Ahhh yeah it's my first ever build! Figured something would go wrong. Does the download work? Thanks for checking it out though!
Yeah I tried the download and I think it needs additional files other than just the .exe. For example, when I built the project for windows the target folder contained the unitycrashhandler64.exe, unityplayer.dll, [project name]Data (folder), and MonoBleedingEdge (folder). I then zipped up the target folder and that's what I uploaded to itch. But ugh, I know it's like to work forever on something only to have it crash on release!
