I feel like this really hit the horror mark for me. It built at almost the perfect pace, going from unsettling to uncomfortable to starting to question myself at the perfect rate and im really glad you managed to complete the full story/game in the jam. I feel like you really explored with and delivered horror without relying on stereotypes or jump scares. There were so many little uncomfortable bits that forced you to just feel a little off or think about somethign uncomfortable without being too direct with the player.
The art was a joy, it was coherant and the asthetic was absolutley nailed for what the game was trying to do. The 3d atmosphere felt right and had some nice touches (especially the head falling off) and did a good job of not working against the game but creating a distinct sense of differtentness, like it was clear it was the 'real world'. The 2s art was great with the main character being super expressive and having bundles of personality through many differnt channels from the vfx to tthe writing. The background were also good and really consistent for selling this feeling of being stuck in a game world.
The music was a little weak i think. The drone was unsettling but without much else to contrast it was a little distracting. The beeping when there was an error was super loud, which did alarm me, but then annoyed me 😅.
My biggest critisism was not being able to skip the text (like being able to skip the animating in) or speed it up in anyway. I know it creates a slow burn but i was finding myself becoming impatient and being a little less immersed because i was waiting to be able to continue. but i think in the grand sceme of things thats a pretty impressive thing to be the issue in a game jam game.
Overall i think the concept was really strong and amazingly well executed to get it all together for the jam! really creative, intriguing and fun. congrats and thankyou!
