For an H-Game this is pretty tame and lacks interaction and rewards. If you're in for the perverted content you'll get disappointed. It's also worth mentioning there is no dialog or plot and I don't enjoy ahegao face. It looks cringe. Aside from that, the girls are decently animated.

Gameplay-wise it offers an actual challenge and for that reason, I'm not rating this too low.

If you're really craving for a space shooter H-Game it's preferable going with Deep Space Waifu.
