I've played the game for quite some time now (like 4 or 5 hours) and the game is very fun. The only problem i have is that the progress seems to slow down very fast after around level 1200. It just becomes too repetivie, getting one equipment every run and a run takes like 10 min (5-10)
There is currently a difficultly spike while playing Stan at around level 600, but other than that the game should be smooth sailing.
