Wanted to find a place to comment since I played the demo.
* Love how the rocket launcher is used as a hazard before you can pick it up.
* It did took me a while to realize I could destroy walls with rockets and got kinda lost.
* But I also love how the seemingly infinite ammo gun works.
* And the enemies, specially the crytal rain one.
* Lot of interesting and cool visuals in the first map alone.
* Also love the "hologram" tutorial things with the mouse.
* I did get lost for hours over the final sigil to pickup until I noticed a shootable crack in that large thick pillar.
Overall, still a very interesting game and I can't wait to see the final result.
