Descent - Insane-max - No Damage - Level 24

Hello, I was experimenting with new challenge, where the idea is not loosing a single shield during the level, not even by contact with walls. Really difficult I would say. And I'm not sure if all levels are technically possible at all... I expected this level to be very hard, but it was actually better than expected. I thought by far most problematic will be area with yellow key, because there are randomly roaming 3 light drillers (and other robots), but I discovered a strategy to consistently eliminate them before they start roaming. Also after some trying I realised I can avoid matcens trigger close to end which helps a lot. It turned out there are other problems I didn't expect. First of all other roaming robots, but also touching walls. I lost many tries because of wall touch. Often I didn't even realised what happened. Also using fusion is tricky. If you are just infront of a wall, your own fushion shot push you towards wall and can easilly cause you a damage. Overally I think my run could be more fluent at some places, but I didn't want risk way too much.. Played in D1X-Rebirth 0.58.1 with keyboard only.
