Okay it took a little while to understand the game:
You have to go up to the coloured Dragoons at the top, and when standing on it, right click on the Dragoon to pick it up. Right click to drop them again.
Then you can drop bombs with left click. You have to bomb the conveyer belt of items at the START of the belt, before they get the shield. But you have to at least have a chain of them going into the center or it doesn't do damage.
Rinse and repeat for each colour a few times and you win.
After figuring it out, it was a solid game. The chain reaction of explosions was satisfying, albeit a bit loud. And lmao at the credits scene XD
