@ those who think it's too difficult:
You have to "power up" the gun by holding the left mouse button down. This will increase the efficiency of the cannon greatly.
thx for the hint, I've tried to improve the instructions. Hope it is better now.
I'm really bad at graphics, and right now I'm still working on the code.
You execute drinking a potion. The regeneration goes quite fast, but not fast enough, agreed. (Maybe some healing spots?) The teddy bear is in the trash can.
