Great game! The graphics are really well done and everything feels pretty juicy! The references to the players are pretty great and you can definitely tell a lot of love went into this game.
My main complaints are that movement is a little slow so levels take a while to get through if you have to start over, coupled with the fact that my save data gets wiped every time I refresh the game. I beat it a couple times and still never got half of the achievements [Though i haven't tried unlocking them since you posted a fix 5 hours ago] . I saw there's a save manager but it's a little confusing with files named things like "JohnnyUpgrade" and "ng_ap_secure_[someHash]"
