Hi, nice game and congratulations ! the game is very dark, but the light effect on the chara helps. Simple mechanics that still offered a decent amount of challenge.We're realizing a video with several games of the Ludum Dare #36. We made the same thing at the previous jam.

Can you add your game on indiexpo.net ? (it's free)
So we can include also your game in the video ;)
p.s. write #LDJAM in the game's description. (you can already find several games from the jam there)

Grids mechanic is really cool, although at first I didn't understood what "grid" is, because they are pretty unnoticeable on the background.
Levels (at least in the first minutes) were a little too claustrophobic for a platformer (it's kinda upsetting when you can and want to jump but there is a ceiling in a few pixels above you).

Overall, a good game, but can't push myself to complete it, mostly because I have no feeling of satisfaction or reward for progressing.
To my taste, your games would benefit from being more compressed, with denser concentration of unique situations and experiences (or maybe I'm just not fan of platforming). Only opinion.

Just completed the game)
Very nice entry! Simple mechanics, but interesting gameplay!
Want to see full version in future!

Hard to understand mechanics with light and clean dust.
Some of puzzles simple to broke...without feature to restart one room. If you kill ane firefly or broke few lamps some levels becomes completely uncompletable... and only way to complet it is...suicide... if u don't destroy all enemies))
