This is a very good game! I played many playthroughs. 372 points were my highest score. At first I found it a bit annoying not knowing which items did what, but later on I really enjoyed the discovery of each new mechanic.
But I do wish there was an option to redraw.
Dissolving something and then having more space for new items also feelt a lot like in Tetris with it's limited grid. Very well done!
