Ok, I tried again and figure out what I did wrong. It is a fun number go up simulator. I got a glitch, Bucks:NaN so I could upgrade anything, but I had already mostly beaten the game by that point.
Thanks! Yeah i didn't expect someone will play so far so didn't check what would happen after upgrading last level. There is no win ending done, so i guess Buck:NaN is a marker of winning the game. )
