Sorry for being not very explicit in my previous post... You've correctly figured first steps:
1. You should blow the crumby wall by the conquer token with the top right bomb.
2. That bomb is only useful while the yellow door SW is down.
3. Once the chain explosion starts, there's no way to stop it. The last explosion would hit the orb which brings that door up.
4. Thus, you have to set off that bomb before the end of explosion chain.
5. However, that most important bomb has a short fuse, and you don't have enough time to run out of explosion range.
6. Unless another yellow door east to the bomb is up and you can hide behind it.
7. That safety door is activated by the orb east to the mimic potion (mouse-clicking on each orb show what it does).

×8. Now you need to plan your path so that you start the chain of explosion, run to hit the safety door orb, run to light the fuse of the top bomb, hide behind the safety door, and you must do it ahead of explosion chain hitting the leftmost orb.
9. Planning a path to the fuse is tricky due to confusing tile graphic. There's a place where you can jump across the water.

×10. For the best path you have to stand below the mimic potion when one of the bombs blow a crumby wall to the orb.
