Really interesting concept and implementation, well done! The art is beautiful and really adds to the creepy atmosphere almost like Disco elysium vibes! The menu screen was great - very responsive with the UI and gave a really polished look. A few suggestions i have that might help improve on this - 1. The gameplay was a bit lacking i felt and you could add some more variety to make it more interesting like clicking on various things in the room with the mouse or dragging something from somewhere to somewhere in the room. This will also feel organic to the theme and add some variety. 2. The game is a bit unforgiving at the moment, you could make it easier by penalizing the player lesser on missed actions or wrong actions or reduce the time between actions atleast initially, and then speed up. This would also give the player some leeway to get used to the concept. 3. Maybe some feedback on if a key was missed - something like a flashing or an error sound could help since its difficult to look at the meter on the left when youre looking at the keyboard pressing buttons :D 4. Voice over for the instructions? I dont know you could try it out, since the player is looking at the keyboard, a voice telling him what to do could also add to the vibe.
Overall though this is a great entry and the fact that you did it in 4 days in a totally new engine is quite impressive! Well done :)
