Quite frantic which can be fun, but I think it was too regular, too much the same experience the whole time, and lacking a bit of variety.
It could have been interesting for example to have some enemies slower but with more health (so that you have to focus on them for some time).
I quickly stopped thinking and just spammed the space bar moving up and down, not really caring about the bombing as I was avoi dthe top part, and not caring what enemy was coming from.
Congrats on making everything (art, audio) during the short time frame !
