I got the exe to work, but I have some questions about things that were not clear to me:

• Do you have to use all the blocks?
• Do all blocks need to have four connections (turn white)?
• Which button do you need to press to test if you did it right?
• How does the connecting with the gray line work? Can the bottom port of one only connect to the top of another block and the left port only to the right port?

Can you upload a browser version, my virus scanner doesn't allow the exe.

It's a little tricky to figure out how it works and a little tricky to play due to the extreme vignette effect. Just made it to level 3 and I'm starting to see the appeal, though! Very cool and creative game system.  I bet a more polished version of this would play really well.

I watched the tutorial (wished I could skip or go back but it's timed without any control)... and I still couldn't beat the first round. I might need the first round to be fully shown to me before I truly get the concept.
