Thanks! For some reason (and it is still a total mystery to me) when we made a build for our game it sort of forced a higher resolution than it should be (which is why things moving look all smooth). In the editor everything is as pixelated as it should be but due to time constraints we decided to just submit what we had even with the bug we were experiencing! Hopefully I can fix this in the future!
In regards to the issues you're having with the Mac build I'll look into that ASAP and try to fix it! Thanks for letting us know! :D
