"Eternium", "Once in a Lifetime" I think, "Fap nights at Frennies" I think.
Now I have to think for a moment because I liked stuff like broken dreams correction center but wouldn't call it a master piece yet.
"Unraveling August" (if it finally continues pretty funny), " Summer Heat", maybe "Ripples" I'm not sure.
I also tried some stuff here and there that I probably don't remember or some other interessting fun games that I just think aren't big or special enough to call them master pieces at this point.
To me it's how good the animation looks, if I'm interessted in actually reading the story and once in a while I feel like I have some art tick which is similar to I just really love how they made the characters and stuff.
I tried my best early in the morning and with no gramar check :)
