Thanks for all the feedback on the game, don't worry about the mac thing, one of my colleagues has a mac from 2008, so it was a bit of an inside joke. Glad to hear the export works on mac though, since I didn't actually test it. Will check out your game when I have time, looks pretty impressive already.
Definitely agree that I should have added an aim assist mode to the shooting, I found that quite a few people struggled to hit the enemies. Also, the water was made using a simple shader that displaced the vectors, not that difficult but it requires learning an entire programming language (Which was a bit of a pain).
Next up I'm planning to work on a more open-world type game, though creating the backend for one isn't the easiest thing in the world.
Once again, thanks for the feedback, it's a huge help!
