Hey Davy! Fantastic job with the first level! I would say I had two issues with the game that I could bring up.
- The responsiveness of the controls are a bit delayed I felt. I would press a button and the character wouldn't swing his fist or jump until a second later.
- The controls were a bit weird to me. I'm not used to pressing enter to fight. I tested it out with my Xbox One controller, however, and it was a lot more fun, but it seemed like I was jumping and attacking at the same time. Maybe you can focus on making it work properly with the controller, since that makes more sense to me for platformers.
