Experience You need try to obtain as much
experience as you can to survive the levels later in the game.
Buy experience points in between levels, unless you have to
spend it on other items to live. Always destroy every monster in
the level. Try to reach level 10 by the end of the game.
Food Save your money and do not buy
a lot of food. If you are skilled, can finish the first three
levels before you are hungry. Also, find the food hidden in the
levels instead of buying it.
