There's a lot of personality in this game (the description, the way Gird sweats when holding blocks and compresses when holding two blocks) and it's impressive you put it all together in only 48 hours! I liked the concept a lot but found the controls a little bit frustrating - the fact that I have to run up in the correct direction in order to place a block correctly was kind of annoying, though it did add a puzzle element to the game which was interesting. I did also wish that there was a stronger, more consistent indicator of which direction Gird was facing, and that it was easier to see the blocks that were behind other blocks, but I have no idea how you would actually be able to implement those features, so. Unfortunately I am terrible at spatial reasoning so I ended up not finishing on time. I was surprised that nothing happened when the timer ran out. I ended up running out of patience and didn't finish the house, but now I kind of regret not finishing to see what happens at the end.
Once again, it's really, really impressive that you did everything in 48 hours!!
