Would love to have a level creator.


Great game, hours of fun, minimal ads, and the ads they have are not videos, so you can instantly dismiss them.


A masterful platformer puzzle. So addictive. So perfect. Been a moitititi fan for almost ten years and Im surprised that a game developer has held our attention for so long.


For a game that was made by a single developer (or at least thats what we think), this is straight-up astonishing. The graphics are great, the gameplay is awesome, and the best part is that theres basically no ads and no pay-to-win. If you get a game over, then you simply have to watch a 2 second ad (at least for us). The stars are a great way of being an in-game currency, and we love how you get one for free at the end of a stage, so youre guaranteed not to miss out if youre not that good of a player. Overall, this game is amazing for one person. Great job, youve earned one of hopefully many 5-star reviews.


So we got the game and got really addicted so Im really surprised that its only got 88 ratings. This game is just simply really good.


It may not be intentional, but one of our favorite features of this game is that when you get a game over it rewards you with an ad with an X. But the fun part is that you can choose characters that have different amounts of health, movement speed, and jump power. We love it because it (maybe not intentionally) has you choose between risking getting ads for speed and jump strength, or be slower or jump lower but have more health (less chance of an ad).


Cant believe this game was made by one person. Great example of a Indie game with a lot of heart. Great platforming. All for free.


Im not the kind of person to write reviews but this game was so pleasant and fun. The puzzles are based around your limitations and abilities as the slime guy and its pretty fun just moving sometimes. There are a few ways to customize your experience as different slimes and animals with different levels of agility, but every challenge can be beaten by even the weakest slime youll find. Personally we mostly just used the cat because his face expresses so much and so little emotion at he same time, juxtaposed against the slimes who are just happy to be here. As you progress youll unlock new color palettes and music, changing the game from something challenging, to some bubbly fun, to something more action-packed. There are some downsides here, like the frequent ads, but we feel Ive enjoyed our time with the game enough that it isnt prohibitive to our experience. If you like fun Id give this game a shot.


This reminds us of mega man in a weird way though we would like a buy no ads option.


The controls are so tight! Such a great experience and so many levels to beat.
