Nice to see a new game from you!
Simple but fun concept that starts easy, but really ramps up as it goes on. Lovely pixel art, as usual. I wish there was a fullscreen mode... I played the web version, didn't see the option.
Great work!
Edit: After looking at your screenshots again, is the Web version supposed to look like this? (The grey box) It looks this way for me on Edge, Chrome, and Firefox. (All PC) Enemies and objects all appear within this grey area, so it's part of the playfield.
