Super cool graphics and really satisfying sound effects. The jumping felt a little float-y, but eventually I came to enjoy it. The ground-pound in particular feels really great to pull off. This is what Mario Run should've been :P Nice work!

Cool game! Great art!

Wow you could do so much with just one button. Nice one. ;)

Very good try, simplified operation reinforces the importance of jumping timing, and is more suitable for mobile players : )

Very fun game. Nice pixel art and sound effects too. I found it a little difficult, but still enjoyable. Well done!

A cute little one button platformer! It plays really well. Wish it had some music, but otherwise well done!

Very fun, and nicely done. I liked the tutorial approach in the beginning, very elegant.  The fact you can't directly control your direction adds quite a bit of difficulty, might want to ease into that a little bit. (Right now, level 1 starts with a tricky pit/hill combo.)

It's nice that you can play with the mouse... the game is pretty difficult for me lol! Very cool app! ^ ^

Graphics is very simple but feels great! I like the mechanic. This game really needs music!

The graphic were great and so was the general feel; loved the Mario callbacks! The slam was a cool way of dealing with the player getting turned around when they didn't want to be too!

I love that pixel graphics :)
At the beginning that tutorial part was a bit boring as player moves little bit slow but then the gameplay is ok...

Fun idea! I liked that the implementation of the slam encourages strategically planning out your double jumps, and that the constant threat of having my direction changed meant I always needed to be aware of enemy placements. Also, cute art and impactful slamming animation. Nice work!
