arg, i should really think before i start asking

For anyone who doesnt know the little trick behind the last stages, here it is :
*SEMI SPOILER*
At the stage where u need to get 5 keys to advance u can exit on all sides. After completing one of the stages there you will be transported to a certain stage on the main map. There you will see that there is a gate in plain sight. That gate will lead you to a TIMED stage where u must get to the treasure chest within the timelimit. When completed you will notice that the number next to your Key will be increased by 1. You will need 5 of those keys to get past the Key-5 stage. But that is not all! on every stage where u can get a key there is also a hidden gate under a moveable block, there you will also get a timed stage. when finished you will notice nothing unusual. BUT for every "secret" gate completed you will get a secret power in the stages past Key-5!
the powers are :
1. Extra speed (now you can dodge the Golls/dragons)
2. Can always shoot (now you can go through the middle by killing the snakes and the cat thingy)
forgot the right sequence after this

sorry

3. Make Moveable Block (now you can make a block so the last medusa wont see you
4. Destroy Block, forest
5. Extra speed (otherwise the don medusa's would be too fast)
6. Create 1 Block (otherwise you wouldnt be able to get past the don medusa's)
*END OF SPOILER*
