Very interesting. The bugs that occur are not sudden, but forewarned, so the player can challenge the situation with some preparation. Fair design.
I feel that the setting where your ship gets bigger with each damage you take is also effective in making players impatient.
The boss battle felt a little unreasonable, as there seemed to be no gaps to avoid at the top.
The music is also cool. The high saturation of the screen makes it a little difficult to play calmly, but overall I think it is very good.
