Let's see...this is gonna sound harsh, especially for a demo, but the game needs infrastructure work before it can continue.
Graphics are ok, but mom looks like she has a guy's head. Just not the right shape at all.
MC and uncle look good. Uncle is not my type, but oh well. Also, just based on the opening, it seems like multiple characters have the exact same body shape with different heads and varying body hair. Which is not going to be good.
There appears to be a way to load a game, but not to save one, which given the lockups, is annoying. But given that the game only lasts about 5 minutes, is ok for now.
Choice to not fap at beginning is not honored in the story line (assumes he did).
No way to increase text speed. It is excruciatingly slow.
No way to change music volume.
Game randomly locks up during Uncle dialog. Might be related to clicking too fast through text? Not sure. Forced to use Windows Task Manager to close the game and start over.
Lack of variety of poses during dialog. Or rather, it isn't so much a lack of variety, as that the ones chosen don't seem to fit the dialog well.
No indication of what objects can be clicked on. Have to just randomly click on things. Clickable objects should be highlighted on mouse-over.
Can't skip, can't go back.
Hopefully the next release will actually allow you to do something.
Edit: After playing 1.1, some elements got fixed. Doesn't seem to lockup any more. Cursor changes to a hand when you can click on something in MC's bedroom, which is ok, but would like to have something more obvious, like the big hand when you click on the dude's pecs later in the game. Can now save, although it isn't always available, and it doesn't seem to always work. Text is still unbelievably slow.
