cool game! wish it was more clear how high each block was though.
my winning strategy was to build a 9x9 grid to lvl1 around the king, then a 7x7 grid on top to lvl 2, and 5x5 grid to lvl3, then a 3x3 grid to lvl 4. then try to build up more but I quickly forgot how high each block was so I just started spam clicking everywhere until I died at 11+ minutes
