not sure why but the game didn't seem to work for me? going by these comments it should be working but i couldn't get anything to move at all (besides the blinding light which seemed to suddenly end my game sometimes despite not looking like it'd touched me yet?) i'd mash A and D and other random keys repeatedly and even press held them down in case that was the issue but the spaceship didn't move a pixel. this seems like the issue's on my end but maybe it's somehow a compatibility thing?
[after going back to judge the visuals specifically] oh my god i just realised you weren't supposed to be moving the giant ship at the bottom of the screen with the monkey we can see inside of it, it's the little galaga looking ship positioned above it. it does actually stop receiving input after restarting though, so that's something to look into.
so, i feel like clarity can be improved here. the big ship we see doesn't look the same shape as the little shape at all, that little ship also looks like a different art style with the pixel shading on it which kinda let it blend into the environment for me. also, maybe try to limit the monkey's peddling animation to when the A and D keys are pressed, gives the player more feedback and it'll look fun.
but the idea of propelling a spaceship forward with a bike is cute, and the input imitating back and forth pedal movement would be a point towards cycling but it doesn't seem too integrated into the rest of the space theme otherwise. i can see that this was just a small game but i see potential in leaning into the bike powered spacecraft thing way harder. designing the ship with stronger bike influence and making it move with weight from each peddle rather than just pixel by pixel along a straight line. make it really feel like you're cycling a spaceship.
anyways before i discovered how to actually play the game i meant to point out that the little ironmouse coloured mouse messing with the wires is a cute little nod.
