Reached the end first try, didn't even use up any lives and barely engaged with the mechanics. I think it's pretty good but needs rebalance.
Encounters are pretty fair despite how chaotic they appear to be. The full wall of turrets having you maneuver across a line of platforms is a nasty bomb bait though. Aggression towards turrets is overwhelmingly rewarding and killing just a few the moment they spawn will let you have much more breathing room - this funnels you into a single strategy for opening encounters.
I'm not sure all spawns are telegraphed, l was surprised when a swarm of the small white drones spawned almost on top of me.
Player is way too tanky. A different way to balance this would be a bit more punishment, less healing opportunities but gradual ramp up in encounter threat.
Edit: I played the old version, I swear I didn't even notice the update notification and wasn't prompted by that to try it.
