Nice game, but very unforgiving.
The switching of bullets, and the absolute control of dashing felt very nice.
The big laser attack of the boss could be telegraphed a bit better, audio wise, like a charge-up sound.
I have the weird paradoxical issue with these kind of games, that it starts very slow, and gets very intense very quickly, and it bounces between these two states, without any in between period.
Good game overall!
