Kuru Panda Thread

Hi fellow developers!

On my christmas holiday, i started to work on a new 8-bit style platformer game.
It's inspired by my childhood favorite Nintendo games, Super Mario Bros and Megaman.
I designed it to work with one-button control, so it would be nicely playable on mobile devices.
After working for about week on code, music and graphics, this is what i got now.

It's called Kuru Panda.

Playable demo:
Kurupanda.com

Demo includes first world with 4 levels, each containing 30 stars to collect.
- Can you collect all stars?
- What is your best time on World 1? Mine is 160.939, with 116/120 stars
- Do you find any bugs? How is performance?
- Does it feel too hard, or maybe easy?

Any feedback would be really appreciated!
