Help with The Legend Of Sanktoh 2

game by 60FourMaster

i got all the items but now i'm baffled...

the only place i can find which uses all the keys is a looooong stretch of water covered by the blocks and i cant find any way to pass it... if i had NO keys i could, but i needed the keys to get the upgrades

I haven't played this level, but when I listen to your story, it might be that perhaps you could only win if you get half or the keys or perhaps all but one?

oh god nvm... i just randomly ran around pressing down and found a house i had missed... gonna explore it and find the end i bet not sure what that place with the blocks is but maybe i'll loose my keys in here

thx anyways
