Excellent rail shooter - movements are smooth, artwork is great and music is ambient. However there are some minor drawbacks - due to large amount of monsters their sounds are a bit repetitive, so a slight variation would be good. After level 13 there is nothing I can buy from the upgrades, so it would be great if could upgrade even more. Some ocassional mini-bosses or some forks on the road possibly leading to the same exit, but with some tweaks would make the game even better. Apart from that - excellent job!
P.S. I think this game was made by Russian-speaking developers, due to label price for beast upgrades (Cena) and a strange tooltip for ammo (patrons!?). What is "glasses"? "ochki=points"? I would love to play the original Russian version (if such one exists) :)
