This Seeking Tech guide will explain how you can beat the Slowdown Showdown level in Astro Bot. Use the following video as a reference:
For the first section, pick up the hourglass and then throw it at the enemy. Afterwards, quickly move past the electric enemies and then defeat the two others on your path to the next hourglass.
Once you pick another hourglass up, throw it again to slowdown time. You then need to carefully avoid the electric enemies and floor while making your way to the next area.
Afterwards, defeat the three electric enemies on the X platform. Try not to go too far ahead or you will trigger the lizard.
Once you are done, grab the hourglass and throw it. You should then quickly make your way across and defeat the lizard.
For the next section, throw the hourglass and then carefully make your way through the cannon balls. Make sure you land in the middle of these balls, or you may fall off. You can then run past the electric enemies.
In the final portion, you only have a short amount of time after you throw the hourglass. So, you need to quickly make your way through the spinning platforms without any hesitation.
