How Do I Pass Level 1-20 in "Mario Forever: Block Party"?

The internet has led to the creation and popularity of independent video games made by amateurs. Some of these games, like "Mario Forever: Block Party," are different takes on old favorites. In this game Mario needs to perform a series of puzzles to destroy blocks to proceed to the next level. The trick is that Mario cannot use his trademark jumping skill. As the game progresses the puzzles become harder. One of these "impossible" levels is 1-20, but it can be completed with a bit of thought.

Instructions

1. Knock the block over to your left once the level starts.

2. Push the first block on the right of the left ladder into the hole on the right.

3. Nudge the block on the left of the right ladder into the other hole. Knock the block under the right ladder to the right and use the right ladder to get on this block.

4. Walk off the block to the right to obtain the bomb.

5. Push the block twice until it passes the right ladder.

6. Go up the right ladder and walk off the block to get another bomb.
