Very skill based movement and creative concept with but the lava sensor block seems to stop working at times (no option to click upon placing it)
2 fun hidden movement techs I found:
1) Jumping at the exact moment after landing can give you a slight boost in jump height. (Can get on the circle block at the start of the level without expending a block)
2) Placing a block just below you in the middle of a jump can sometimes result in a super jump with massive momentum (very fun to do)
