This game was honestly amazing and I loved every second of it. Honestly it's one of the main reasons why I wanted to create an itch.io account - so I could comment a review because before I just lurked and downloaded games that interested me LOL. The small details in the game really enhanced my enjoyment of the game and I loved going through all the endings and spending time with all the Milos to see how they changed and I apologize in advance for how long this comment will be.
Giving the Milos their own animal sound effects really subtlety portrayed how he changed as a character with Pre-Milo being a rabbit, showing his meekness and how small he felt. Which then he slowly changed into a dog or cat depending on the violence or manipulative route respectively. Violent Milo being given the dog noises accentuated that guard/protective feel and fierce loyalty that violence Milo has and also his commitment to his owner - Eris. Manipulative Milo having the cat noises helped show his change into becoming more cunning and intelligent. How Milo could be agile and stealthy like a cat in social settings.
Other details like the music and the art itself (and I absolutely ADORE the music and cgs) also helped create the game's haunting and eerie atmosphere and made me feel more immersed in it - I felt like I was at the edge of my seat sometimes because I was wondering what Eris wanted to do next with Milo and how far Milo would end up going for them. And some more details I found that were cool were actually in the games code itself! The small things like the MC's names and nicknames you could give to Milo were really funny and nice to read. I dug around a little bit and saw there were hidden messages in the beginning of the game and at the end of each ending that were in morse code and another code (that I'm still working on decoding haha) and they were really really neat to read.
I also really love the the MC/Eris being fucked up, it's not something I seen often, especially in yandere games and I think it was done really well! I also really enjoyed the sort of dramatic irony-ness of cheering for poor cute little Milo but knowing that he would slowly become corrupted by and for Eris.
This game is for sure going to stick with me for a while and I'm excited to see any new things in the future if you intend to do anything more!! With this game or if you intend to create anything else. I'm very sorry for this long review LOL but all in all I just wanted to say I really enjoyed this game and playing it a lot.
