Originally the game was supposed to have a lot more mechanics than that, but since I don't have much gamedev experience it took me a while just to make the basic mechanics right. I still feel stupid for forgetting about QWERTY keyboards....
Hey! I'm really sorry for the inconvenience! Since I work with an AZERTY keyboard, I wrote the controls only for this type of keyboard! If you're using a QWERTY, the shoot button should be W. Thank you for your comment and sorry again!
Oh my GOD I'm so sorry I completely forgot that I wrote the controls for AZERTY keyboards! The shoot button should actually be W if you're on a QWERTY! Once again, I'm so sorry I didn't think about this! I'll update it in the page's description! Thank you for your comment!
