Cool idea with a decent execution! Here are my playtesting notes:
+ Reset mechanic is interesting, the diary is a good way to keep track of clues, and replaying to alter events is a fun central mechanic.
+ A surprising amount of well-implemented features for a solo project, from the UI to the menus to the insertable character name.
- The text is too slow, it needs either the base speed increasing or a button/click that then skips it. It took me 23 mins to complete, and I think that would have been 5 mins quicker if I could read at my own pace.
- Some of the writing is a bit clunky, so if you wanted to polish this up I think you should go through and do some grammar + quality checks on it.
Good work!
