Hi there, I ended up downloading and playing (with another machine that already had directx runtime installed) and glad I did. I thought you nailed the theme, executed it really well (no bugs) and was fun to play. You hid the keys really well, not too hard or too easy to find.
These are my main points of feedback.
- There was quite a few different controls to remember, might help the player to show them on screen at all times.
- I don't think I ever needed the flashlight or jump to finish the game. I would consider removing these mechanics or make them required in some way to find a key.
- Might help to show the text of a note as soon as you pick it up as opposed to requiring the user to go in to the inventory to check
- Also, I noticed that the text in the inventory gets cut off for items on the far right
Hope this feedback helped, great job overall :)
