This version includes some things, including some new stage
the lag
To avoid lag I should stop shooting As long as I have many enemies
Sometimes I start shooting As long as I have a specific enemy (I don't know how lag works XD)
Strategy
I used the same strategy in the same publication I didn't do anything special
15:58 I manipulated some meteors to fall off the screen to avoid lag (I'm guessing those background meteors are causing the lag)
