This was a really fun game, you should be proud of yourself, great entry!! It feels very much like one of the flash escape room games I played back in the day on addictinggames or something (that's a good thing). The presentation is great, it has hand-drawn flash game aesthetic that fits perfectly with this type of game. The puzzle mechanics were fun and made sense logically, when something happened it always made sense and felt reasonable. Finding something in the mouse hole at the bottom of the wall was a really cool moment (although I have to question whether a broom would actually fit in there lol). The Dexter easter egg was a great touch too.
The attention to detail in each scene was impressive, there's lots of little details like the blood splatter on the walls or drool on the snarling dog that make everything feel well put together. Some sfx or background music would go a long way to improving the overall atmosphere, and the clip you posted in the discord with music does a great job of that. Unfortunately, I got stuck after finding the scissors but until then I had a fun time exploring the world and figuring out the puzzles. I'm also curious about the secrets of the arcade machine.
Overall, I think you have a great start to an escape room game and adding some sfx/music and finishing out some of the puzzles (scissors, arcade machine) would take the game to the next level. I really liked the hand-drawn art too. Awesome entry, keep up the good work!!
