Pretty interesting start! I'd love to try more. I had some glitches with the bullets where they didn't start from my character's position and I couldn't shoot up or down. Still, I enjoyed the simple graphics a lot!
Thanks for the feedback on the game. Glad you liked some parts of the game.
P.S.
I will think about how to improve gameplay. And maybe I will also improve the architecture.
In any case, I am very pleased that you played it)
