There's some potential here, but I found myself getting a bit annoyed with the concept in the later level's. Getting from point A to point B involves a fair bit of RNG to begin with given spawned items to bounce off of, adding in mortars/shock drones only adds to that, resulting in more arbitrary frustration than amusement. That and the mortars/shock drones seemed a bit out of theme.
The angle i'd suggest would be to lean more into the ridiculous, instead of mortar strikes, why not leap into the pool during the middle of an active hurricane/tornado? That way you could add in theme specific items like wooden planks, cows, or all sorts of things flying around. Or you could even have a scenario of the player jumping off a spire into a pool of lava in hell, or during an alien invasion, city on fire, zombie apocalypse, an atomic blast, into a bottomless void, or *insert ridiculous scenario here*, each with their own unique challenges.
You could also try implementing wind currents to catch to stay in the air, as there are many times when getting between buildings hinges on RNG from a lack of items to bounce off of (watch out for giant planes). Or perhaps kites to grab to provide the player with slow/drift to help wait out the RNG for more favorable items to jump off of?
