Awesome Anatoliy! I particularly liked how you got the rats to look like they were running up a slope there at the end when they came out of that gully - very nice effect. Can I suggest you actually block the pillars in the first room. Having to fight around them, while the enemies behind them appear and disappear would add something, I think. (If you have tried this and it ruins the encounter due to being a small room, then disregard. Also, apologies if you spoke about this, I had the sound down fairly low while watching).
