use wasd to walk around and space to shoot, use your mouse to aim towards the enemies, there are three enemies and guns, the first enemy is red and if you kill, you'll get 1 gem. Secondly, the blue enemies give 0.5 gems and is fast. lastly, the orange enemy is slow and will give you 2 gems, but if you touch you loose 2 lives instead pf 1
sorry I haven't been making games, a lot of things has happened and I just want to say, I'm back and I couldn't have been more happier.
