Idk: the boring platformer

There are 5 secret codes in this game. You can type them in by clicking the not so well hidden code button on the title screen. by entering the codes, you can get either 1 of 3 skins, a rickroll or a message. The codes are scattered throughout the levels in hard to reach places. Well some are in plain sight like holbo, being one code. I wont tell you the rest tho but I hope you will be able to find them.
