This was surprisingly super engaging with a simple but great take on the theme.
The good:
The game gets going in level 2 when the 'laser' attacks come into play and they actually was surprisingly welcoming as I remember being quite surprised when they appeared.
Being able to move a small platform is a great take on the theme and adds a lot to the strategy of the general bullet hell (and also becomes the cornerpiece of gameplay in level 3).
To improve:
I would love if the character has less (or even no) inertia in their movement. Bullet hell games require a high level of precision and control over the player avatar. If it takes a long time to move a character to max speed, it is hard to control them.
Surprisingly fun!
