Fun execution and very fun pixel art! I do find the game is pretty difficult though, reminds me of NES games with their secrets and stuff. Overall neat premise, but I did find myself stuck one too many times to beat it. (Though I did appreciate that not everything reset when you die)
Overall I feel that the difficulty could've been tuned down a bit, maybe make the headphones recharge rather than be a pickup with a counter? There are a lot of projectiles to deal with and all. I also had trouble moving down platforms after having jumped on them (ex: ladders) and some of the colour choices had me confused what was and wasn't a solid object, or they sometimes blended into the background.
Overall solid stuff, and the fidget spinner is a neat idea.
