The tutorial level wasn't much of a tutorial, but rather more like almost impossible to win. I think some kind of slow tutorial to explain the mechanics was needed.
The janky movement of the player does not fit well with the bullet hell coming from the enemies. The player almost has to be almost perfect to even survive the level.
I found that level 3 was my favorite because i could string together attacks to create the combos - the idea for the game. Since the enemies were only one at a time, at distinct angles from one another, it allows me to move correctly to beat them.
