I really appreciate the effort you've put into this project, and I want to be honest while also encouraging you to keep going. Right now, the game feels more like an early prototype than a finished experience. For some reason, the left arrow key doesn't seem to work (even though the others do), the enemies don't react or interact with the player, and it's unclear why the player character dies.
Additionally, there's currently not much incentive to keep playing — features like a scoring system, a timer, changing levels or enemy behavior would really help bring more engagement and variety to the gameplay. As it stands, it feels a bit repetitive.
That said, if this is one of your first game projects, you're definitely heading in the right direction. The foundation is there, and with more time and polish, I believe you can turn this into something great. Keep at it — you're learning and improving, and that's what matters most. Best of luck, and keep creating!
