Thanks for playing, and for sure, playing Boulder Dash as a kid was the main source of inspiration! I did focus on a slightly different kind of levels than the typical BD fare, shorter and more single-puzzle oriented. I think that helps define this as its own thing with its own personality.
Thanks for finding the restart count bug, I'll look into it asap! Might be related to restarting from the menu, that's not something I do.... ever :-) The game actually has a restart hotkey, on the keyboard it defaults to hitting 'p' twice. You should hopefully get a little hint about the existence of the hotkey any time you restart from the pause menu. I will think about how I can improve the communication around this further.
