Hey, nice game... actually to be honest I'm more than slightly annoyed at the wizards... but setting that aside...
Was trying to get past level 2. I'm fairly certain it is not possible in the current setup. It would have been though if a certain bug (eat slime -> full slime) mentioned in previous comments was still in the game... consider adding another patch of no-cost travel terrain to level 2, or possibly allowing the player to succeed on the 12th move.
To be clear, what I deduced was that it takes 16 moves (8 horizontal and vertical) to make it to the opposite corner, but the player will die on their 12th move-payment, regardless of if that move would have meant victory. So, assuming that each move is a step toward the goal, we need to have greater than 4 no-cost moves. But I could not see a path that offered a low enough cost to offer survival. Feel free to point out if I am missing something.
