I really like the style of this game! The main character is great too, and adding a blinking animation goes a really long way to make the character feel like a living part of the world! Getting launched with the canons to the next area, as well as the background hills really reminded me of playing New Super Mario Bros for the DS and Wii, so that gets nostalgia points from me [:
The movement and platforming felt pretty good, and the trail effect was really satisfying when reaching high speeds. I kinda wish that there were more bouncy mechanics, as it fits spin tops, and could add a lot of cool ways to clear certain parts of a level is designed well. I think that going for slippery movement is a nice choice, but I kinda wish it was sliiiightly less slippery, and that there was a little bit more air control :b
All in all this was a great entry and I enjoyed it a lot, nice work!!
