This is excellent. Insta-buy. Two suggestions:
- There seems to be an obligatory waiting time before start. I wish I could just play again faster
- I feel the collision on the player ship is a bit large. In game like Dodonpachi or other bullet hell shooters, the collision for the player ship is usually smaller than the sprite, which lets the player be more bold and it feels much less punishing
But, again, this game is great. Good job!
