Imagine you buy this amazing game, which is extremely well polished and has plenty of content, mechanics and abilites.

Then imagine the devs went fuck it and gave you three more entire games with their own unique characters, movesets and stage layouts, all for free if you owned the original game.

This is one of the best platformers I have ever played, and I have 100% completion in all 4 games. It's a must play if you like retro style platformers but with modern controls.
