Really beautiful and high-quality game with an interesting concept. But it's genuinely challenging – managing the cubes on the raft without any pauses is pretty tough.
It's cool that you can try out different strategies in the game. For example: at the start, gather a huge number of cubes and stack them vertically to pick up as few as possible and just survive on that stockpile. Or do the opposite: build a long line, just one cube thick, so the damage is minimal and you collect everything. Or you could build a mega fortress out of cubes...
