Thank you so much for playing my game and for the feeback. In Steam version game is much more stable but for some reason the web version has some glitches and I am not updating it since it takes time and probably there will be some other glitches, too. That said you can try out the game on Steam for the latest version. There will be some more additions to the game in the full version like new purchasable weapons in market and it will be better for sure.
