This Seeking Tech guide will explain how you can beat the Let It Slide level in Astro Bot. To rescue both bots, you need to beat the red bird, which will take around 50 seconds to reach the stage exit.
Use the following video as a reference:
When going down the slope, stay on the right side and then jump and hover to the right.
Once you grab the ice, jump towards the seal and then use your powerup. While you can try directly jumping on the seal and have it boost you upwards, it is a tougher jump that requires more precise timing.
After creating the ice platform, jump to the next section with the spinning spike.
In the next area, you should jump off the second ice platform and then use your powerup to make your way to the cliff.
You should then use your powerup to get to the ice pool across the waters.
Afterwards, use your long jumps and powerups to get to the ice platforms at the end of the stage.
