Possibly one of the strangest acid trips you will play this year, kanoguti's I.R.P. is an adventure game where players would have to figure out the solution to the puzzle found in each room, simply by using the right combination of buttons on their keyboard. Every playthrough yields a different set of random sequences, so by replaying the game you might find some new areas that were never discovered in previous attempts.

Please note that the game has a couple of scenes with flashing images which may cause photosensitive epilectic seizures. You can also press the Alt and F4 key to quit at any time. (direct download link)
