You know I wouldn't say they're glitches, but just exploiting game mechanics, managing health and good pathing haha.  But here's a list of stuff that could help you improve your score

1. Your own bombs deal 1 dmg to yourself, big dragoon bombers deal 3 dmg and snipers deal 2 dmg.  You can mitigate the extra damage from enemies if you just bomb yourself.
2. I don't think the barrels placed in the map actually do damage LOL.  I think I messed something up when I was trying to fix some stuff during testing.
3. You have 0.5s of i-frames after getting hit.
4. You can blow up the red trains next to you for just 1 dmg which isn't really a big deal.
5. In Section 2, You can blow up the big barrel pile and then use the big dragoons to quickly die and respawn while the explosions are happening. (I'm actually not sure if this is faster than just running, but you do get a full heal from the respawn).
6. In Section 3 with the large walls, it's hard, but you can shoot the barrels near the snipers to activate the gunpowder trail mid-way instead of the very beginning.
7. I think one of the red trains after the first boss isn't actually connected to anything so you can just skip it (oops).
8. During the jump at the final stage, you can land on top of the train on the right and skip the initial walk around.
9. At the final stage, you can simply skip the right side of the map after clearing the first red train and just blow up the big barrel if you place a bomb at the very top corner.
