PapiHop is a free game from Yohei Iwasaki of Sunflat, where you control Mr. Papi as he bounces uncontrollably off of different-coloured platforms. Your goal is to hit the platforms and avoid falling past them, losing the game. It's similar to Pong, but with more direct control over the character. Mr. Papi is also featured in many of Sunflat's other simple free games.
