Graphics and music: 10/10 no complaints at all but nothing interesting either.
Gameplay: 8/10. Synergises pretty well with a porn aspect of the game. I like how sex scenes in this game act as a reward in so many ways: as a checkpoint, as a health refill and as a resting period for the player after some pretty stressful attacks.
In isolation, the boss is perfect, with my main complaint being inconsistant visual feedback. And by that I mean "what do I need to shoot". Generally, you shoot boobs, they bounce, you make progress. EXCEPT FOR THE FIRST PHASE. I did not struggle with this as much but it still could have been done better. We have a similar problem in the final phase, but because the target then flashes each hit it's not that important. The easiest way to solve this issue is to simply add a health bar for the boss.
Other thing I can nitpick is the fact that keyboard and mouse controls aren't equivalent, with the mouse being noticeably faster. I mean, many shoot' em ups do this because mouse controls instead of directing where your character will move simply teleport them to the position of your cursor. Not in this case though: the speed is higher but not infinite. Pretty annoying mechanic, and not negligible like the unclear visual feedback. I have no Idea why this is the case.
My final complaints are: I want more, and I want downloads, but those aren't really complaints, are they? Therefore, they don't affect my final score: 9/10.
And yes, I've beaten it with keyboard only with no hits. It took me way more than 0 resets and 6 minutes because I used page refresh instead of ingame retry to save time. In reality, it was probably about an hour of attempts. GG
