Some semi-on-the-fly remarks!

Remarks:

1. I like the music. :)
2. Ah, the square seems to have non-decreasing inertia when jumping/hovering; which may be fine, depending on how you want the playability to feel.
3. Colliding with the vertical brown bars makes the square ‘teleport’ higher; are they some sorts of ramps?
4. Space does not seem to work for jumping (it does apparently nothing), BUT the Up arrow key allows me to fly! And this does not decrease the jump counter. I think this is a ‘gamebreaking’ bug, as it allows the player to completely bypass the limitation on the number of jumps (and makes navigating your way super easy! Super Cube ;)).
   [Space does actually work sometimes, see further below.]
5. Ah, you must CLICK on the die to roll it! I think this should be made clear somewhere, either in the game or on the game page.
6. Funny, you can collide (including climbing on) the die! X)
7. There are few levels, but this is no problem as it serves demonstrating the concept. And it would surely have been longer for me without the flying bug!
8. Even without flying, I am wondering how you can finish a level if you get few jumps on the counter; I also noticed I was allowed to reroll the die, but then, it amounts to have an infinite amount of jumps.
   If this is the case, I would advise making it harder to reroll; for example, rerolling makes an enemy pop, or decreases your health, or any such limitating mechanism.
9. Relaunching the game: ah, Space works at the beginning! But once I run out of jumps, this time, I cannot reroll the die, and I have to resort to the flying mechanic… :o I think you need to allow the player rolling the die when he gets to another level; and also to restart a level, if you want to prevent him from rerolling, because otherwise, he is stuck (or should be, without flying ;)).

The idea could be interesting, but there is definitely a need for something else to counterbalance it.

You also need to fix what is apparently a ginormous bug about the jumping-flying! ;) I understand you uploaded the original game jam version, so maybe you did not have time to check or correct this back then.

In conclusion, this is the sketch of a concept that needs to be fleshed out. Keep it up, you can certainly improve the game. :)

Now that the voting phase is over, could you please upload a working version of the game? Sorry you could not apparently have it corrected in time, but I would still like to play and review the game. :)

You need to include all the other files made by Unity, not just the .exe. I am unable to play your game.

looks like nice idea, if you develop it more could be a good game, gg!

Just like Koce, UnityPlayer.dll missing… ._. Can you ask for a resubmit, since you were apparently authorized to join back? (Edit: I mean a file upload rather than a resubmit, sorry.)

By the way, I like the choice of the books for the ‘walls’ on the screen captures! That’s rather original. :) Somehow, this makes me think of Super Castlevania IV’s library.
