The game is super pretty! But a bit too easy. I literally didn't understand that I was picking towers before round 1 and only picked the Reimu tower, and I was still able to win.
Despite being easy, the game is also weirdly punishing in the early parts of the stages, where I found myself unable to do anything except watch Yoshikas mow down like 3 towers in a row due to tower building cooldowns preventing me from building anything to stop this. The talisman comes through and saves the day in this scenario, which is how I never failed a level despite not know what I'm doing.
