it first i thought htis game was going to be very boring, and it was for the first 10 seconds, problem is ... I kept playing it !!! dude this is soooo addictive I couldn't stop upgrading and watching these cubes go around, the balancing ofc needs some balancing but this is no easy tyhing to do in a jam, and the single tile speed upgrade works fine when u only have one, but if u have a couple of cubees it gets a little clunky.
One more thing that woulda helped imo is a color change for each tier (fade of red for example)
Great game man
