Enemies
There are only two enemies in the game but I figure I should mention them.
 * Bat: It doesn't attack you directly. Instead it drops stuff onto you in groups of two or three. It hovers above a small area but there is usually other obstacles to avoid as well as the bat droppings.
 * Ghost: A pretty weak enemy really since it's slow moving and easily destroyed with your gun. It appears after awhile if you live long enough.

Obstacles

 * Geyser: There are two types of geysers, ones that shoot out steam and ones that don't. The steam will kill you so you should wait a second or so when you approach one to see if it does or not.
 * Pit: There are two types of pits too, open ones and concealed ones. Open pits you can easily see since it's an open hole. Concealed pits often have a narrow stretch of ground covering it that will collapse when you step on it.

Screen Info
All information that you need can be found along the top of the screen when you're playing the game. BOMBS #  SCROLL # LIVES #          MINMAX SCORE ##### Everything should be self explanatory but I'd like to mention your energy, which is the long bar to the right of the SCROLL. You start with full energy meaning that the arrow is next to the MAX on the right. As you play the game, that arrow will gradually move to the left and when it reaches the MIN, you'll die and have to start again. You have to collect energy tanks to make the arrow move to the MAX again.
