102 waves completed.. got no more buildingspace and the waves rarely make it to the first corner of the path.. It's hopeless alright, but not very difficult.
Found an exploit! When you get to Otis's letter you get a regen-potion. When in that position, save the game and exit to main menu. When you load your game again, click on the position you stand (the letter), and you will get a new regen-potion! :D Repeat as many times as you like ;P
