Hmmmmm, pretty nice game. For some reason, I couln't see the crates in the WebGL version, maybe my brain not working or something else, even tho I tried backtracking.
So I downloaded the PC version, and the blue forcefield was there, and it clearly showed that there was something around here to do something. And I zip-zoomed and quickly got through the game.
I think it is the different rendering and lower framerate of the web version that causes it to not feel as good.
But as for the actual game on PC, I like the whole dynamic all three weapons bring. Pretty nice, short and sweet game. Good stuff.
