you gotta love google :)
here we go:
The Keys
OK, you are by the road with the truck circling around. Don't get run over! One of the side roads makes a sharp corner to the right. A large house there has "GENERAL STORE" written on it. Press the space bar to open the door. From the store, there's two ways you can go. Facing the back of the store, there's a way to left and one to the right. Going to the right, you should come to a split in the road. Take the road that leads to the big barn with the sylos (tall, large cylinders). On one of these sylos there's a bull's eye. You should have picked up the dynamite in front of the general store. Press the #5 key to take a dynamite in your hands, press Ctrl to light it up, and press Ctrl again to throw. Now press Shift and the back arrow key and get your ass out of there as quickly as possible, before you blow yourself up too. Those dynamites have an aweful aim. There should be a hole where the bull's eye used to be, go through there into the barn. Go up the stairs, the first key is on one of the straw bales. You'll have to do a running jump (press capslock) from one of the other bales. If you still can't make it across, use moonshine if you have it (press M) or increase your RUNNINGSPEED setting in your USER.CON file (see section "Some general info" for more on that). Now with that key you will be able to open the back door inside the general store. Inside that room you'll find the second key (somewhere on the floor). Push the bookcase to the right for a secret area. With the second key you open the cellar. To find the cellar, say you are at the general store, go towards the barn, but instead of making a right toward the barn make a sharp left toward a house with a well. In the cellar you'll find the third key. The third key opens up a house close to some marshes. To find it, go on the road that's circled by the truck. Go on one of the side roads, make a left, and you'll find the house. Open the door with the third key. Bubba is in one of the cabins on the marshes. Hit him with the crowbar to end the level (press number key "1").
The Secrets
Here's all the secrets in E1L1: one is revealed in the demo (from where you are at the very beginning of the game back up all the way to the hedge - secret is in the hedge just few feet from the corner). Second is in the hedge next to the house with cellar (use your map to find exactly where-press Tab for map). Third is inside house with cellar, in the fireplace. To get to Stanky's, start from where the first secret was, before you get to the General Store make a right, and then a left at the fork in the road. Jump on the dumpster, then onto the lid, and then on top of the building. Fifth in cellar. As you go in, go all the way to the back, turn left. Facing that wall, press the space bar and a secret door should open. Sixth in the store. After you get the first key, go to store, open the back room, and then push the shelf for final secret. 1
