The movement felt so smoot and nice. I had lots of fun playing. My first game I ran out of ammo, but the second game I beat with like 4000 ammo left. I really enjoyed it, but I felt like while I was shooting the upgrade menu came up and then I would end up clicking the middle one. I feel like if you added a confirm button then you couldn't accidently buy upgrades. I still had a wonderful time, nice job!
