Great job. Constructive criticism:

1. Sometimes the "hitbox" to hide under a table seems a little too small.

2. When hiding, the game is so dark it's hard to make out what's happening.

3. There are a few English grammar mistakes that I'm sure will eventually be corrected.

Everything else is simply amazingly well done. The opening credits song is good too. This is one of my favorite releases in a long while!
