I love the art so much. Eli is really cute and adorable in both of his ways ^^. The way that he breaks the fourth wall it's also really cool. If you could add something more "messy with your computer" (like closing the game by itself, creating text files, putting the name of the user of the pc on the game, etc) it would gain a lot! (but I understand that's a really messed up thing to code, and there are also many ways to break the fourth wall, but I think that this suggestion could make the game a bit cooler ^^)
One thing I was surprised about it's the fact that it goes straight to the point. Even during the warning part, you can guess something will go wrong eventually. I thought it would start off sweet, by meeting Eli, chatting a bit with him, getting to know him and then, out of nowhere, PLOT TWIST. Eli starts getting obsessed with you and all the glitchy stuff happens. (I hope you can understand what I meant xd).
I think that if you could get a bit sweeter in the beginning and then boom all the creepy stuff afterwards, it could be great. But if you want to, you can keep the creepiness in the beginning and maybe try to go even deeper and darker into Eli's background!
This was my honest opinion, I hope it can help you with the development of the game! :)
