preety charming visuals and i find the level design to be quite good.
it definetly is on topic, but i found the "ai companion who shoots down aliens for you" to be - excuse me for the term - quite lazy and badly executed. the "gun bug" also ruined my experience, and at the end i was swarmed by enemies and left with absolutely no ammo.
try also not putting an arbitrary (and very short) time limit, especially right at the start of the game - that's a really bad design decision imo.
