This was fun! And harder than you'd think at first. I never got very far. I remember a golden X falling from the sky and avoiding it, but thinking back that's probably an extra life no? When I see a big fat X my first instinct is not to collect it, but to run away from it.
I like the choice of assets, Kenney doesn't miss. Keep working on this! I'm curious to see how you'd expand on it.
