Wonderful game that kept the challenge fun. Got a bit frustrated (in the best way possible) as the challenge increased gradually, not too quickly, nor keeping it simple until later levels. You definitely used minimalism to your advantage.
Great game. Message at the end was a bit weird though. How did you do the water? Is it some 1d brownian motion kind of thing, or is there no randomness whatsoever?
Water tile checks if there is a white/fire tile left-right and if it's true it moves on it. The randomness is in the choice of the first direction, sometimes it chooses right, sometimes it chooses left.
eh... I apparently set a level I was making a few times without hitting the submit button !!! (unless I hit it as I was hitting the try button, which is in the same spot.)
Anyways.... The level creator is nice, but It would be nice if blocks did not move around when I try to place them. Can be a small pain when you delete a block by mistake, and see them all start moving everywhere.
Also, the water (blue blocks) seems way to random to me. One minute it keeps hitting the lava (red blocks) and not going though it; then later, it finally stops going back and forth and goes though it.
Besides that, I've been having fun playing this game.
Thanks for the feedback :)
Let me know which level you want to keep and i'll delete the others.
I uploaded a new version, now you can pause the game pressing P (and place them quietly)
Good puzzle game
