Cool thanks for playing my game ^^
Sadly a as a puzzle "platform" design in mind, it doesn't give too much liberty for the player to navigate the levels, but when I start adding more movement mechanics the player will naturally have more options.
About the controls, there is an alternate mode to walk in planets just using the left and right. I may change for it to be the default as a lot of people prefer.
Will surelly try your game too and leave some feedback/suggestions.
