3 stars for this is very good. It's about a 10 minute (if that) porn meme.
Character models: 4/5
Slightly sad about the mario growth, but still cute.
Characters: 2/5
Mostly joke characters but somehow they had a decent personality setup.
Sex scenes: 3/5
(bad animation, not enough changed between frames, not very erotic focused)
Sound: 3/5
Most of the sound was obnoxious, some of it was slightly amusing. I did smirk at the ara ara.
Plot: 4/5
For a singular scene, a lot happened. A bit too chaotic, but if it were a bit smoother and more erotic focused it may have been a memorable scene.
Humor: 2/5
There were moments it was amusing, but mostly annoying. I think the scenario itself was funny and there were some singular puns or references that were funny, but the over the top tongue in cheek of it was... too forced?
If this had a lot of content... well if it were exactly like this I would end up exhausted and close it. But if it were toned down on the ludicrous comedy, I could see this easily making for a good VN.
Enjoyment: 3.5/5
Amusing-ish, and kind of sexy, but not very erotic due to the comedy.
For a proof of concept this is pretty good.
