Oof, sorry about that man, I built it using Godot and it's WebGl compiler uses the new language web assembly, so I'm not sure how well supported it is outside of chrome. I do need to get a mac version out there though, I will dust mine off and get that done this weekend.
Glad you enjoyed it though! I will probably be doing a bigger version of this game soon, I think customization etc would be really fun to add
