GunBlocks: Prologue

This can be quite hard/RNG based but i have one quite helpful tip:

If you fall down the chasm before the last section on each track, a drone will pick you up and put you to the right side of the chasm next to the finish line.
Unfortunately you cannot fall in the chasm just by yourself, you need one of the drones shooting an explosive barrel (that destroys the blocks below you) at you.

You cannot do this with the normal shot, you need either the 3x3 or the other shot enhancement.

Fortunately you can get the 3x3 shot right at the start of the first level on the left side.
Just get the upgrade, save it, wait for the drones to be lined up and use it to hit all 3 of them.

Keep in mind that you can manipulate the height of the drones by putting blocks at their current position.
