Easily one of the best and trickiest platformers around, Slime-san is a seriously underappreciated gem. Another big update recently released, adding in a level editor.
Honestly, I don't understand why it has so few reviews and followers. Slime-san is practically one of the best platformers around if you're looking for a true challenge that won't be over quickly.
Have a look at all the tricky things you can make with the trailer for the update:
Thanks to this update and those before, there's now hundreds of levels spread across multiple campaigns all with their own unique challenges to face. Different play-styles to unlock, local multiplayer, an awesome soundtrack, various hub-worlds to explore with mini-games and when you get bored of all that the level editor will let your creative juices flow (or try out what others have made).
As part of the Slime-san: Superslime Edition, the level editor is a completely free update and like all big updates before you can also purchase it by itself. If you've not played it and you enjoy platformers, you're missing out on something awesome.
