I really love the art style especially the hand drawn opening scenes. I'm really not a fan of the style of game however that forces you to fail several times so you can build up skills/money/whatever to just gradually upgrade yourself to eventually win. I prefer to have a fighting chance or have winning be based on my choices/skills etc rather than just repetitively increasing numbers. But maybe that's just me.
Still it was fun once I got some upgrades and then eventually I could just AFK complete the game without even dodging.
