Heya! You got a ton of reviews already I see, but I wanted to give my two cents anyway ;) First of all, the art style is very simple, but it works! Well done! I have some regards to the controls however. First of all, I would scale the ratio between drag distance and jump height down a bit. I felt like I had to drag really far most of the times. Also, let the player drag from any point instead of just the player: Lets say the player is near the bottom right edge and I want to jump to the top left. if I can start my drag from any point, there won't be any issues. These two points would also save another issue: The screen resolution of the device you're running the game on can now determine how high and far you can jump. Furthermore, the arc of the jump feels a bit strange. Finally, if I run out of power after making a jump, I can't finish the level anymore? That felt a bit unintuitive.
I don't at all feel negative about the game though. It is simple, but that also means you have been able to execute it very well! The graphics and audio are good, and there's quite some content.
Well done!
