Matchblocks is fast, furious, and potentially painful, a pretty good combo in a matching game. So yeah, come for the bright shiny colors-they're worth it. You'll end up staying when Matchblocks teaches you just how fast your fingers can fly.
Matchblocks is where I like to see puzzle games heading: it's a very different execution, and it works extremely well. Don't let the word "Match" in the title be off-putting, this is not a match–3 game and it stands on its own as a fun original concept.
