I loved it. The animation for manual, the old school internet music, the low-effort voice acting and the wonky artstyle melt together very well. The UI part can be improved a bit, such as label the bar as oxygen/wait time and label the food in fridge, but it not that big deal. Suprisingly, my favourite part of the game is reading and enjoying the manual. Great job!
Btw, is the music you make yourself? It's really catchy so it would be great if there a standalone version of it.
