After playing the fixed version, I must say that the game is very fun!
The movement is VERY clunky though. When you release SHIFT you shouldn't instantly switch speeds, it should be a smooth transition. This is pretty jarring.
BUT! I like the graphics, the environments (Dejvická metro my beloved), the sounds and music are good, although they could use a bit of polishing (i literally cant understand the AI voice), even the chaning music enhanced the experience a lot B)
Also (nitpick), there's no reason to use the rocket launcher and pistol. They should be buffed!!
Few ingredients are used, but they're pretty well implemented. The castle! Sacrifice!
For a gamejam game, very fun. If polished (a lot), this could be a fun retro shooter!
