Really fun and creative! Awesome use of procedurally-generated islands.
The cnotrols make my hands hurt a bit and feel a bit awkward, and the game seems to crash when you try to teleport without having a full charge.
Really fun game tho, my best final height is 116m. I lived with one literal health point left for the longest time. It was really exciting. And then an island broke the tower I was building and I plunged to my death.
One cool little thing, would be some sort of warning system, that warned you of the proximity of islands to any section of the tower you are on, so you know if you need to move your butt or risk getting yeeted. Of course this is only a suggestion if you decide to expand the game later on!
Fun stuff, enjoyed it.
