Very fun and nice game!
It definitely got nice visuals and music. The core gameplay became really clear after the first level. The game has a nice order of levels, and some levels (especially if you wish to gain all 3 stars) can be difficult. It is really good at making you memorize the path of the boss. It felt nice when the music was changing.
Personally, I would have liked the increase in difficulty (for example, maybe you could add more managers and make their path less predictable, but that is just a quick idea).
Overall, the game is really nice and it made me complete it from start to finish (it was addicting, one might even say).
