You are really doing yourself a disservice by not including all the controls in the description because this game is fun!
Just for people that want to play, either read this or experiment with the buttons!
Arrows: move
Z: jump (you have multiple jumps in your green mode, check the bar at the bottom left)
X: dash
Wow this game controls great! The 3d movement works well and is really smooth. Figuring out the movement was a really fun progress because I felt like I kept unlocking more moves. The levels also really forced you to experiment. There was the one where you had to jump to the end without your green form. This jump is impossible unless you dash. This is how I figured out the mechanic.
When you are in the green mode, you are really powerful (having more jumps etc) but you balance that with restricting movement in certain area's with the green blocks, giving atleast some reason to switch back.
Visuals really remind me of mario 3d worlds look, which I love! Also, the music is a classified banger. Gives me a real sonic colors vibe.
Played it to the end and I really see potential in the mechanics. Would advice giving a bit more thought on tutorialisation (either with text or buttons showing on screen or making a really save area where you are forced to use mechanics to proceed).
