I already told you how much I liked what I've played so far...
...I just hope we'll get to play the actual maze part one day, especially after the cliffhanger ending of your demo! :^^:
It's a nice level, but it feels a bit aimless.
I didn't think to go right after reaching the umbrella, so when I reached the screen with the spiky enemy covering the portal, I got frustrated and quit. It didn't help that there was an annoying sparkle-spraying enemy on the screen before it. My suggestion would be to take that enemy out, and add a couple more save points around the level.
Besides that, I thought it was a really lovely level. I hope you finish it one day.
