I wouldn't upload the development build of your game, dude.
I couldn't finish because I am stuck on the level with the purple blocks. I don't know the language (Brazilian? Portuguese?) being spoken here, if instructions were given verbally, but I couldn't pass that level using intuition (maybe mine is just bad lol).
I was very surprised the game was as fun as it was, I almost skipped it completely, because of the graphics. While I don't expect amazing pixel art, but I do expect some type of animation to it, I didn't even know what the main character was supposed to be, since I played without reading the description.
I do understand it is an 8bit pixel game, but you can make that little robot look better with some work on it, like adding wheels that has some animations to it or something? Or rocket fire that comes out whenever it jumps? Even Mario Bros for NES had some cool designs and animations on the characters.
Aside from the sprite for the main character, I did like the look of the whole game, you have a good concept here.
The game was fun and kinda hard if you don't play platformers like me. The little drift with the characters whenever he moved right or left added to the difficulty which was nice to see.
I think you have a nice little gem here if you took time to develop it.
