Interesting mechanics. Later blocks dynamics are a little confusing, but I completed it anyway so I guess it's just an impression.

Nice puzzles but a bit difficult to understand what each new block does right away.

Solid puzzle game. Liked the music.

Nice. BTW, restart button is bugged: after I restarted level, I wasn't able to move water blocks anymore.

A fun puzzler, but the restart seems to be broken in the sense that if you restart after blocks have interacted (e.g. fire and ice blocks) the blocks which were removed won't come back.

Really nice game.
It's a simple concept but it has a lot of variety and the graphics are really good.
Great job! :D

pretty cool game, there seems to be a small bug with the controls though, if you want to quickly go in different directions

Best puzzle game I've seen so far in the competition. Good job!

Great idea of blocks having different reactions!
Transitions between states (like after ice block has been pushed it would slide to the target position) would be nice addition.
And if I restart the game after I have melted ice to water, it will stay as water - i.e. the level is not reset to the beginning.

Restart button is indeed bugged (water blocks don't respawn) but overall this is quite good! I enjoyed it.

Well polished, though for me it was a bit flat as it was basically a sokoban clone and those are just... EVERYWHERE.

There's a slight problem with identifying a block and its intended destination or what they do - in the beginning when there's only a block and the goal, you can understand it, but later it becomes very confusing - if the visual link between objects, their destinations, and what they did (i kind of see that happening with the ice slide block that's supposed to look like ice).

Also animation between a push and the end of the move would help communication too - again - the ice block just teleports to the end of the row, which is confusing.

The bugged restart makes it hard to play the game properly. As Tuism said, it's also difficult to identify which block is meant to go where. It takes a few tries and if you accidentally melt the wrong block... Well, you have to refresh and try again from the start.

Overall, though, it's a good game and, despite the bugs, is well made and fits the genre well.

Nice take on the classical sokoban type of puzzle. I like the 3D effects on it all and the difficulty progress was really nice, though I got stuck after a while. Sounds and music also very nice match to the game.

Things to consider:

It took me a while to understand the mechanics of the many of the intractable objects. E.g. the blue and those that canceled each other. I think it would both be clearer and cooler if you added some lerps or tweens and some A and B negates each other effects. That way the mechanics should become more accessible.

It was nice with a retry button and really nice that the levels had checkpoints so retry didn't always mean from the beginning. The graphics of the button didn't really match the rest of the game though (very minor detail), and more importantly, it would have been nice if 'R' invoked the button. Some levels you want to hit it often and you shouldn't force the player to use the mouse when it's not used in game.

Finally, it would have been cool and clearer if the tiles of the playing field flipped over at the end of each level (rotating 180 deg on whatever axis, maybe by random or some order) to expose the next. At the end of the first level I was kind of confused by one of the disappearing symbols and though I was supposed to remember their positions.

All in all a great game and some fun playing time.

Fairly straight-forward game. Nice level design, nice speed of introducing new concepts, and 'tutorial' levels or sections to teach players these concepts. Nice job.

Sokoban never gets old :)

Game glitched in level 4, when I restarted the level the win condition was kept active, so I couldn't get past that level. Anyways, nice game :)

Unfortunately I got stuck since after I restarted a level, a water block became immobile.

I love the face of the slime block! The music was also nice.

Nice Sokoban game. Interesting use of theme.

Took a while to understand the blocks. Animations of the block would really have helped, now some things just seemed random in the beginning. Also, if you turn around quickly you might be sent an extra step in the wrong direction. Actually quite nice puzzles though!
