"Go to bed" Oh my God, I was actually playing this at night ahaha. Okay, so sorry for the spam in the comments section, I'm usually one to hate spam myself, but this game has got me hooked!! Make a SECOND ONE PLEASE <3
Level 4 guide, SPOILER ALERT: push your right hand against the right wall. Using your left hand, push the top heart onto the right hand. Now, using your Left hand again, go all the way down and underneath the bottom block and then turn your Left hand to the right. Your palm should be right underneath your Right hand, atop which is a Heart. Now, simply release your Right hand so that the Heart falls down. Using the Right hand again, curve down and push the other heart, which is between the two blocks, onto the other one.
Level 3 guide to those who are stuck: SPOILER ALERT.
First, press 'D' until the left hand has reached the block. Press 'W' until it reaches the top of the column (but do not let it exceed the column's height, have it leveled with the top). Press the Up Arrow Key and level your right hand with the Heart on top of the Column. Then, pressing the Left Arrow Key, push the heart onto the Left Hand. Press 'S' to drop your Left hand to a slightly lower level and then reverse direction, pushing the heart until it is right above the other heart. Now, simply release your Left Arm until the Heart falls onto the other one. :) I hope this helps!
This reminds me of the Legend of Zelda: Minish Cap's dungeon puzzles (particularly in the Temple of Droplets). Anyone else feel that way?
Anyway, this is a great puzzle game, 5/5.
Tip for newcomers or anyone who is struggling: start from the Red Circle (which you want to turn green) and work your way backwards. Look for double negatives, ANDs, ORs, etc and try to discern which switches need to be turned on/off. Always work backwards.
Okay, now that I'm farther into the game I've realized that this is an EXCELLENT introduction to boolean logic and digital circuits. You should make more levels or even make a sequel!
Really cool game and a fun introduction to digital logic. I would suggest improving some of the definitions, though (for diode, I would mention that it allows energy to pass in ONLY one direction; I was a bit confused by the game's definition until I Googled what diodes are). As for the puzzle concept, it is fresh and appreciated.
4/5
