Clever game idea that is super simple! Only thing I have to say is spam pressing a button is a pain point for people who have RSIs or other wrist/hand injuries. Fits the theme really well.
Thank you! Yeah, it may not go well for those people. I may rebalance the game increasing the pump amount so it does with fewer key presses. The feel of the game would change from "having stamina to pump" to "may I pump once more or not?". Gotta try it later
