In progress
-When i saw the whole detective thing at the beggining i was like "whoah cool! clue finding!". Instead i got some very generic puzzle which didn't follow the plot at all.
- I found the DOWN KEY feature really interesting, but it wasn't really usefull to any lvl other than the one it get's introduced.
-There were also some minor glitches where you would stuck in a wall sometimes.
+You should make the levels more challenging, e.g. Lock the doors and throw around some keys that's you'll need to open them.
+Add some clues that's you'll need to obtain in order to solve the mystery
+Work around that DOWN KEY feature. It's pretty interesting.
All 'n all, it seems like this game is still in progress. It has very nice potential if you work on it a little more.
Hope this helped.
