Really nice platformer game!   Did you use Godot (Godot user here)? I liked the fact that you included a story/meaning to the game, it's not only "go from point A to point B of a level" but there also is a task! The movement works great (a bit floaty, it fits a low-gravity planet, maybe not earth) and the game runs smoothly, and nice title screen! I also appreciated the how-to-play section with the little cute object instead of writing the word, it's a nice and convenient touch!  The levels are quite big that, in a task-based game I think is really good!  Maybe sometimes I felt a little lost in the level, going blindly (maybe also because you see only a little part of it, I mean only some platforms or even no platform other than the one standing on) but this can also be used to encourage exploration and makes the learning curve/understanding of the map-layout stepper (that could be also good)! With some polishing, some more little animation, and maybe adding a little more variety can be a really good and fun platformer game!  Nice job!

There was only one thing I would change, that you could jump using the spacebar. Overall, pretty good platformer game, I really enjoyed it!
