One thing that I thought could be improved was the color of the objects in the scene. I understand that the platforms matched the nimble mode and the blocks matched the aggressive mode since they should be interacted with respectively in their own modes. With the lighting change, the platforms look almost completely different in the modes. The blocks however, look almost the same even with the lighting differences. To me, the red blocks seem out of place in the joyful mode.

In the first mode, the red color is a really good representation of aggressiveness, so is the background music. I like the idea to convey “strong” by allowing the avatar to push the boxes. But from my point of view, the avatar is still not strong enough :D, it seems that the boxes take a lot of strength to push. But the feel is definitely there.

In the second mode, the fastness of the avatar absolutely shows he is nimble. A little suggestion would be to make it a little bit slower to make it easier to control. The jump is also a bit high and it takes me a whole lot of time to fall onto the platform.

Overall the project is really in good shape. As npai mentioned, the last suggestion would be to make more animations on the avatar. Focus on the details 🙂

The first mode (aggressive/strong) certainly does feel appropriate. The slower speed makes the character seem more menacing. The ability to push boxes is also good at relaying that feeling. The color change to the red theme is appropriate for the associated feeling, and so is the music.

And the second mode (joyful/nimble) is also a fair representation of those feelings, thanks to the increased speed and jump height. The fact that you can’t push the boxes is an indication of the weaker character, but the ability to jump around certainly makes them seem more athletic and energetic. Once again, I like the color change to blue, and I like that the scenery is color-coded to show to the player what objects should be interacted with during a particular mode. It makes me think of Mirror’s Edge, and how it highlights the objects that are of interest to the player.

If I were to make a suggestion, it would just be to add more animations to the character, even though you did mention the time constraints. It would be cool to see the character idly sway or otherwise move to indicate what state they are currently in.

Other than that, it did what the requirements asked and had two distinct feelings. I had fun running around in the joyful/nimble mode, jumping towards the boxes, and then switching to the aggressive/strong mode to smash them apart!
