I don't know how many fans have played this game yet but it's a new game in the pony platforming project series at dragon mango with a greatly improved engine. So far I loved playing it and they even released a level editor for it. I don't want to spoil much of the game in text. But if you guys have played it why not post the levels you made if you made any.
It's a short fun platform game with great music choice, and a level editor.
