Without any doubt one of the best games I've played so far (And I tested around 10 games)! The idea is super original and I loved the concept of musical scale. At first the game seems a bit random but the game has a lot of strategy. I survived until Wave 17 just after buying the purple (2g) tower. This was super fun. I think with a bit more polishing and a tutorial it could be a great game that I could play on steam! 5/5/5 rating!
