For being only a small little demo, this seems really promising so far!
So far, this game seems real intriguing for sure. The whole idea of testing out medicines and writing down the symptoms is a really cool idea for a game that tbh, idk if it has been done before. If it has, this would be the 2nd time at least for me.
The story also seems really intriguing. Doing this to pay off debt and facing consequences when failing.
The graphics and sound design were stellar. No qualms with those at all. The game also seems to run really well. And the sequences in the demo are well done as well. Smooth and no weird glitches or bugs.
This game seems really promising and I personally cannot wait to see the full release! Made a video on it.
