How the heck is there this much content made in four days?? This is really good, could absolutely see playing through a more polished-up version of this with a few more mechanics for hours on end. Really great, simple, easy-to-understand puzzle game that's very fun to get through the entirety of.

If it were up to me, then extra animations (namely making the block smoothly accelerate to max speed, then flatten out a bit before coming back to full size upon hitting the wall), some particles and slight screen shake when you hit the wall that increase when you have bigger blocks, and a few more sound effects, just to make the base gameplay even more satisfying!
