Copy/pasting this from r/playmygame also
"Yeah, you're right, it can be upgraded as much as you want and even offscreen enemies. I totally agree about the UI too; other players also said it's hard to spot the coin and ammo count where it is now. I'll try your suggestion. Thanks for the feedback! I'm planning to publish it on Steam, maybe by the end of this year or early next year. Hopefully it gets more attention and wishlist when I upload the demo, lol."
