Very cool idea, very good execution! I'm unfortunately not smart enough to use the mechanics to their full potential, but this was really well done.

The main gameplay of firing light in a laser then reflecting, diffracting or compressing it to fight enemies is cool as hell, and the objects (densouls iirc?) that you've given us work wonderfully to make it happen. I had no issues with the combat, though I do think the healing was extremely slow compared to the speed and damage of the enemies, I didn't end up using it much. The actual mechanics of the light worked really well, and a concept like this in a jam time frame would definitely be prone to bugs, so I'm quite impressed at how cleanly it functions! I would suggest changing the placement button from CTRL to maybe SHIFT for a web build, I CTRL+W closed the tab a few times lol

Graphics were nice and simple, I liked the enemies and the way you used actual light in the environment. The enemy sprites were good, the player and the beam look sufficiently unusual for it to feel like they're not from the shadows like the monsters are. The beam looked good, though potentially could've done with some more FX, e.g: hitting an enemy, hitting a densoul. The audio was good as well, the beam sounded as strong as it felt and it all seemed pretty consistent! Again, maybe some more FX for hitting the enemies could help juice the game up a little.

I did also notice that the game uses pixel art in some places, and line art in others. It's not a huge deal for a jam game, but it could definitely enhance the visuals a little bit if you made them all the same- the majority of the game is pixel art, so maybe making the text and densoul particles pixel too could tie it all together a little more. I do think that maps with pre-placed densouls could be a cool idea too, so that I'm not limited in power by my own stupidity as much :) Could potentially add some depth and strategy to player placement too if you need to work around what's already there?

Overall liked this quite a bit!! Gameplay concept and execution was really cool and the rest of the game fits it nicely :))

This game is a lot of fun!  I spent about two hours trying to optimize my laser.  This game has great visuals and awesome music, and a functional tutorial for a jam is impressive!

The biggest piece of feedback I have is the player needs to be placing the lenses more often, and I think destroying a placed lenses should refund at least part of its cost.  I placed down a lot of mirrors only to find out they weren't quite right, but destroying them would be a waste.  I only destroyed ones that were actively harming my setup.  I played the game for so long because I was enjoying myself, but if you juice and polish it just a bit more you have an absolutely banger game.

Full marks from me, great job!

Very unique mechanics. I had a lot of fun combining the mirrors (+other densoul) in clever ways. I appreciated the tutorial, and it was very clear on what to do. During the actual game I wasn't entirely sure how or why I was unlocking different densoul (sometimes I just had one available, sometimes I had all three, and it seemed random). I found that the game was a little bit too dark for my screen. The sound/music was excellent. 

Just tested your game !💥

Hope you enjoy it, best of luck!❤️😊

Loved the game! You can get some pretty cool and crazy combos, the enemys didn't have much luck aha.

Very good interpretation of the theme!

Fun little innovation on the Vampire Survivors-vibe, and really clever theme interpretation!
