Haha it's interesting that you mention unlocking them because that's 100% what I was planning to do. I was going to make it so that you'd unlock them at round 5, 10 and 20. I did run out of time for that system but I love that you intuitively thought that's what you were meant to do. But yeah tutorial moment would have been a good idea. I've tried to include the tutorial for controls in 3 different places on the pages now but I don't think it compares to having it in the game itself.
Thanks so much for playing <3
