Thank you for playing :) Yeah originally I wanted them to disappear on the wall and show the changed state of the puzzle so you knew it was done, but I ran out of time. The first puzzle kinda did it showing the smiley face... but I sorta put that on the back burner as something to finish up if I had time. Also I did the animations in a very stupid way, to animate the guys on the walls I'm actually flipping the entire block back and forth instantly to different sides, so I thought I only had 4 frames of animations to work with :P Turns out there is a way to just animate on the blocks, so that part will be much better once I do that :)
The hallway one is a tad tricky, it's the only one where you don't directly control the Sparknoid, look at the dude then turnaround, it's just a switch to hit :)
Thank you for playing again, I'm happy you liked it!
