Pros
+ Nice puzzles
+ fitting soundtrack
+ easy to acces inventory
+ mystic flair

Cons
- Sometimes puzzles are too hard
- soundeffects (not Music) kind of annoying, movement sound to loud, pickup sound actually hurt my ears once (could also be my fault)
- no plot at all (just minor annoyance though)
- Music could be a bit longer (loops too much)
- could open inventory and puzzle pieces at same time (bug)
- the room left from the spawnpoint (beginning) has a black dot on the wall, that is very misleading
- item interaction with the crusher has a too small error margin, needed 5 tries to crush it evetually

Neutral:
0 Graphics are rather dull
0 eye room aestheticly enriching and adds to atmosphere and misleading, but not for to long
0 Kunai (Ninja throwing knife) seems rather out of place

Summary:
Decent Game with some flaws, you can likely get all but 3 pieces without the help of a walkthrough.
for 15 minutes well spent i give it 2.5 Stars.

If youre stuck, that is not a screen, thats a showcase with jars in it. and, not the syringe on that one.

Details:

pros:
+ in general, all puzzles are solvabel through thinking and patience (as opposed to part one)
+ Graphic is nice
+ pickable objects are easy to distinguish from environment

cons
- Door will dispaly open but handeld closed if both are up
- Placement of keyboard not clear enough
- BSoD at the end
- acoustic ambient in general non fitting to the point where muting is a must
- you (as the player) should give some indicator when the screen flashes red
- time limit (beath by Virus) should be implemented
- Notes and other stuff should lie around as background information

Final Verdict:

Half Decent Game with strange BSOD at the end
for effort thats 1 Star

nuff said.
