The game is actually pretty cool! One thing though, I was playing on the keyboard, and it was not immediately apparent that question mark key was to fire the weapon, took me like 10 minutes to figure it out hah. Nice little retro platformer!
I actually like it, it's a good game! I'm actually working with a good friend trying to make a game like this, but more detailed and specific with story/theme, but even using the same engine, etc. I'm glad you shared the link for it.
So if by chance you'd like to work together/collaborate or something, please let me know.
If not, no worries either. I know we all got busy lives going in different directions, no pressure.
