i don't normally give 5 star reviews on this site but this game has something others with fantastic physics, graphics, music, and mechanics don't. optimisation.
so my computer is very old, it can barely run most browser games nowadays, yet this game ran fantastically, i assumed it was just because it was older so it was built for weaker computers then i realised the coins were laggy in their colklection and most of their frames skipped.
this game actually has processing priority unlike most games on this site, or even in general and that is impressive. cudos!
