I was playing on ps4 when I managed to glitch out of the room/level and end up on the actual tower of guns, I climbed it and at about half way I got two upgrades so I'm assuming the Dev thought people would get them and reset (one was luck, what does that do btw?. I carried on and after a few minutes I managed to make it to the very top and recieved a message along the lines of ' how the heck did you get up here, well here's a bunch of stuff since you like breaking games' and got red coins and a bunch of damage and jump upgrades. I was wondering if anybody else has managed this or knows about it, and I'm wondering if there's any other secrets like this (I randomly visited cake town on the run before this one and one time after going up that pipe to the next level I fought three of those organ things?) crazy stuff great game
TL;DR glitches out of level climbed tower became op
