A great idea with a lot of potential! I like this new trend of textless games, though in this case the UI could be a bit clearer on how things work (many thanks for the explainer text in the description). Pacing is a bit slow at the moment and progression feels very linear. My one significant gripe is that you're meant to be making the blocks to create larger shapes, but the speed at which you make smaller shapes has no impact on the build speed of larger shapes.
