It was fun and addictive, and also quite hard. My best is level 10. Most of the time I was killed because my dash ability did not work. The bar would go down and the character even animate as if he is dashing but nothing actually happens.
I think the walk speed should be a bit faster as you can get cornered by drones easily especially in later stages when drones are fast and can predict your movement.
It also felt like the upgrades did not go proportionally to the difficulty increase in each level, but I guess that's the intention so you strategize.
