Nice game, I had a few clipping glitches with the blocks just like others have mentioned, but it didn't ruin the game entirely. Good use of the theme through Portal inspiration too. Great job!
Thanks for playing - can you share a screen shot of this "clipping glitches" - Was this on the web build or the windows download ? I am keen to fix this if I can find it.
Do you think that using E to pick up and put down is correct or should putdown be on the left click on the mouse ?
