Hi, I just completed a playable demo of my game 'Eldritch's Gate' (working title) and I'm looking for feedback.

I have made 14 levels so far, which would be the start of world 1 .
Also, it saves your progress so you don't need to finish it in one sitting, you can continue from where you left off in the Scene Selection screen.

Short Description: 
Utilize drag-and-drop powerups to make your player jump, dash, or change directions strategically. Try to get to the exit with the less amount of powerups as you can.

I'm looking for any feedback for:

1.  Overall gameplay experience.
2.  Level flow (difficulty curve etc.)
3.  Gameplay mechanics difficulty (should I include more helpful hints, is it easy to understand what to do etc.)
4.  Any bug or issues with the game.
5.  Length of the current levels (how long did it take you to complete it, it will help me know how many per world I should include)
6.  Suggestions on improvements and anything you hated or liked.
7.  Any other feedback would be greatly appreciated!
