I liked it overall, but if you want some feedback, the game becomes pretty easy and monotonous once you get the homing bombs after a few upgrades, which I think they should be harder to obtain. You are giving them away too soon and too many at a same time (I got 3 upgrades in matter of seconds) and afterwards they do all your job killing everything on sight. Also you might wanna remove the limited time on fighter selection, I think it's pointless and doesn't allow you to see every spacecraft in detail. Anyways it's fun, reminds me of R-Type times.
not bad but a bit boring and its to easy its shoots automatic
ok but to common
the game is fast pace but over used and repetitive
also very easy
