@Robert: i tried your way and it worked great.

Now i was on the island and i took the shard. a few secs later i heard that the hydra boss was coming because many fireballs and bullets appeard and background-music changed but the actual hydra didn't show up.

I staid on the island for 2 minutes and then i took the raft and put the shard on it (that took me a while but it worked). Then i sailed to the last island. When i bumped into the land, my raft bounced high in the air and fell on the island, but the shard was gone (probably launched in the air). :cry:

Why didnt the hydra show up and why do rafts bounce angainst shore :?

P.S its a pitty you cant save and load the game.. That would make the game a lot better because it is a very time-consuming game. I had to claim the pc for 1 hour to play the level, because you cant easily save and let someone else work on the PC.

//--edit

The raft acts weird when used with a budge-spell. If you make it fall on the ground. it will sometimes replace itsself in the air and fall 3/4 times one after the other.
:? You should take a look at this
