Fun little game. Really nice lighting effects and solid controls as well.

Sound effects would certainly help improve things, Falling straight past ladders feels a bit strange to me. Maybe either have the top of them act like solid ground (Then press S/Down key to climb down.) or automatically grab onto them if you fall past one. :)

Looks very nice

What I liked:

• Very cool lighting system 
• Solid platforming controls

What can do better:

• Game juice. SFX for explosions, particles.
• Not much of a game yet, but solid ground to build upon
• Would be nice to have the character face the direction of the mouse

I had fun with this:  movement feels good, light effects are satisfying.

If I could change one thing, I'd add the fullscreen button (in itch settings) or change the itch page background to a dark theme.  The white background on the itch page conflicts with your dark theme.

Nice work!
