fun idea that was challenging enough to keep me engaged but not discouraged! impressive amount of art and sound for solo dev too! the controls could be tweaked just a little to make it feel a bit more natural, maybe add a little bit of momentum to the jump movement, or reduce the amount of control you have while in the air. I found myself over-adjusting a lot because of how much control you had in the air. keep it up!

Cool idea. Levels were quite hard for me. Just lighting up and jumping could be challenging at the beginning. Might be cool to start with even easier levels to just get used to the concept. I was not sure what is the health regeneration mechanism, if there is one. 

Would be nice if the light cannot be used all the time. If it was limited in some way.

Cool entry, keep up good work !

Cool concept and execution.  I think the jump function should be gated so that the player cannot hold down the button to continuously jump in a row.  It messed with my attempts frustratingly.  I think if I could jump with my left mouse click and toggle the light with space bar or right click, maybe that'd feel better.  Nice level and sound design and I didn't find any graphical glitches at all.

You certainly got some neat little things going for you, like using darkness to obscure information, and using light to show/hide objects.

Well done for a solo dev. That means you'll have to shoot higher in January!
