Not often that you find a sidescroller like this. Surprised by the look of it. If I had some critique it would be the sensitivity of movement sometimes, but I guess that if you are slowed down it sorta cancels that out.

1 thing doe, is lvl 3 broken? seems that one of the lasers doesn't turn off.

I really like the spooky atmosphere and pixel art, especially in level 2.  The music had a lot of energy and spooky vibes - i like the theatrical elements, like people screaming & laughing.  It would be cool to hear the same songs mixed with a Game Boy / 8-bit sound font

the collisions feel a bit unforgiving, and the scaling issues ruins the visuals on full screen :/

Also, very cute

Really cute game!

I think the concept shines the most in the second level, where the palette really brings the collectibles and hazards to attention. In levels where the palette is more subdued, stages can get a bit busy and hard to read, which can impact players' reaction times.

I found the mixed resolution between different assets to be a bit distracting, and think it detracts a bit from the otherwise very well drawn art.

Lumina is ridiculously cute! I love the parallax scrolling on the backgrounds, the eerie music that goes super hard, and the simple concept of an auto runner wherein the adorable vampire girl main character is trying to outrun the light. 

As for constructive feedback, a lot of old school platforming games I think players would expect simple collision, but there were a handful of instances where I found the character had gotten stuck from jumping in a manner where it rubbed against the side of an object, especially the crosses. I also missed having sound effects, I saw a sound credit so I'm wondering if perhaps there are sound effects that glitched out?

That said though, I think the second stage, the hospital, looks so striking with its contrast between GB black and green and the bright reds, plus the music on that stage is magnificent!

I look forward to seeing what you all come up with next!
