I love the update on the game, although I also miss a bit of the whimsical feel of the ver1. I like the new introduction and the new sprites, as for game icon/banner, a sliiiiight suggestion for the artist handling it, it might need more sharper highlight, because the sliding path behind him is a very similar color, we need him to pop very strongly and not blend into it for it to be visually clear. That's especially important for marketing.
The new cover of the game is stunning, I also like the new style direction of the sprites you got going, as for gameplay, got stuck very early on, (check VOD) might need hints and clues for someone who don't play this genre often. lol
I want to revisit it later with a longer run, and give it a proper feature for your game.
