Making a custom engine project in just the last two days of the jam is an incredible feat, major respect for pushing through and submitting it! The minimalistic visuals are really pleasant and stylish, it sets a very unique mood right away.
If I had to give a bit of feedback, the buttons in the menu blend in with the background quite a bit, which can be a little confusing at first. Also, giving the story a little more room to breathe and expanding on the player's choices would really elevate the whole experience. You definitely have some really interesting ideas here with a lot of potential! Great job on finishing the project!
