An interesting, if semi common especially for this theme, execution of a game. The level design was.. interesting, though the difficulty curve I was able to experience was somewhat weird. And the controls were a bit weird in terms of the jumping with the white combo'd with the darker character pushing it. Though once I understood it it was relatively easy to execute and was an interesting but weirdly explained mechanic. Which never quite got the same use from what I saw in the few levels I could.
To finish off, on the topic of levels, it seemed as though the third level was near impossible if not actually impossible. Due to the fact that the jumping character was on the right and the moving character was on the left of a giant wall. With the coin at the top of the left and the exit at the bottom of the right. I couldn't find anyway to move up with the moving character so I was pretty much stuck. Not sure if this had an intended solution? Since if there was it was definitely not conveyed in any way whatsoever.
