You’ve got something potentially very addictive here. The loop is simple, side to side, bash, jump, slam, but the balance is what sold me. The number of runs I had that came down to the last 15, 10, 5 seconds before ending in a death is a testament to the tuning. My final score was 1253.

Those weak boxes though, I have never hated and prioritized something so much at the same time, they led to so many of my deaths :)
A couple thoughts if you keep building. A small tutorial covering the buttons and the box types would smooth out the first run. And I could see extra modes doing well here, something like a slam only mode, or boxes that make the raft list to one side when the weight stacks unevenly.
What’s the top score you’ve seen so far? Trying to figure out how proud of 1253 I should be. Also, do the different boxes have different weights or is it just the amount of hits each one takes?
