The lack of sound is a big minus in this game. Not just music, but sound effects, indicating when I've jumped & stuff like that. A lot of people commented on the color, and I think it's alright. The red MC is fine, but using only shades of red &green makes things blend, and doesn't give a varied color experience. Also, the fact that everything is square & a grid is hard on the eyes.
The checkerboard squares killing me is confusing, not properly explained, and unexpected. Depict 1 subverted this well with spikes being helpful, by using the dialogue & level design to reinforce this, making sure this was something the player understood. The checkerboard squares are confusing because I don't expect checkerboard squares to kill me, and isn't explained properly to do so. I suppose you may have done this as part of the deception theme, but feeling deceived and feeling cheated are not quite the same.
About the other squares, what do they do? I collected one at the beginning, but is it a power up? A coin? Again, a sound effect here would help greatly to define what I have picked up. The end of the game mentioned nothing about them, so I see no purpose in them. Could you explain?
When I turn left or right, I also move a bit to the left or right. This is not helpful. Also, I did experience a few glitches, hovering a bit below a platform once, and completely disappearing at the end of some platforms (mainly the see-through ones). Also, some sections are too small to accommodate for the MC's high jump, especially with the box placement; jumping over them causes me to hit the ceiling and fall right into them.
The load makes things a lot easier, I must say, but it was not made clear that it was an autosave function, and I didn't have any idea until my third restart.
Good on you, using different color boxes to indicate the end of the game. However, the deception theme is nowhere (and cheating the player doesn't count), and the "interaction" you claimed in the description was very limited.
