clear!!!
i got a bunch of cactuses and a bit of mushrooms (as you can see), so that i could attack more while dodging the projectiles, and getting a bigger combo
when you get hit or if you take too much time, you lose the combo, so the cactuses really helped, the mushrooms also did but not as much
the porcupine and lightning bolts are really good when you use them together, as they absolutely decimate crowds
the magma is just there, a bit mid but nice to have
quick edit: the cactuses are a really good damage-dealer when you just fully attack
also items play a role in this, i used the most healing items, focused around hearts, so i could heal well while fighting
the ability (stone wall) is also nice, you can use it to despawn projectiles (like the homing bee the honeycomb shoots) if you cant dodge them
