Great cyberpunk atmosphere!
You packed a lot in to a jam game, from multiple levels to attack and health boosts to... Tim, the cat eared NPC!
I hate to say anything about the art but overall I would say it's a bit too dark. I found my eyes were straining due to the clash of bright neon compared to everything else. I know that's the aesthetic, of course! But that, combined with how detailed each and every asset is, made it difficult to differentiate background elements and relevant gameplay objects. Enemies and walk-able areas don't pop against the equally intricate decorative touches.
There also appeared to be areas that were completely unreachable; chests that I found no path to. Unless I missed a double-jump upgrade or a jetpack somewhere?
