I made it to day 5! (and failed because I bought a new tank by mistake ^^)
I was a bit puzzled at first because I tried to find scales (or treasure) in the first area, before realizing it was just for clocking out.
I would have liked a bit more quality of life features (maybe auto-pick scales, no enemies right next to a door when you change view, etc.), but the controls and the art are nice, congrats!
