CloneUp

A pixel platformer in which the thing you build with is a copy of yourself. Press a key and a clone appears where you are standing; it does not move again, so you climb on it, stack another on top, and use the pile to reach a ledge or block a run of spikes. The puzzle in every room is how many copies you can spare and where they have to stand, and since clones are finite, CloneUp is about budgeting yourself. Restart is one key, and you will need it often.
