Seems like Fit Puzzle Blocks but improved. :) With a bigger assortment of levels too... not sure if it's just me getting used to this type of game, or if the levels really were simpler... but they felt simpler. Didn't get stuck on any one of them, though did have to think things through a bit more with the later ones. The empty spaces add variation, but I imagine they probably make things a bit easier at the same time - there aren't so many ways you can place the different pieces.
Feels like either the angle/ease of moving blocks around has improved too or I'm more used to it too now, since it definitely felt easier here. The mechanics are smooth, the sound's good, the visuals easy on the eye... puzzles maybe not all that elaborate but I really enjoyed this one too!
Nice work again.
