But how to bomb the weakpoints up the top>?
Viewing post in The Cog with no Machine comments
either catch some projectiles and then use the chain orbs on the side to send the gear up to the top before energy runs out or catch projectiles while it is being sent up. The cog fragment upgrades are very helpful, you can also get quick spin which lets you jump higher and if you absorb enough projectiles while jump high you can reach the top ones
That one is pretty difficult and has some tough timings. The game was made in a month and that challenge wasnt playtested very much so I apologize for the imbalances in difficulty. To get the targets underground you have to throw the gear to the right into the right wall and then run left so that it hits the purple arrow on the way back. The rest of them you either use the bombs bigger explosion from absorbing more projectiles or the throwing/warping ability to hit targets inside of walls. The part at the top is pretty difficult with all the hazards, it just requires some precise warp timings.
