Pretty cool!  I like the old raycaster feel =).  I didn't managed to escape after a few tries, my health dropped without me noticing getting hit (I guess, shots from above?) and then it was too late.  I wasn't able to figure out if there was any indication of which places I could go up and which I could not, so often found myself next to a wall that I couldn't climb and needing to backtrack, which was a bit frustrating.  Enemies were really cool looking, and I enjoyed the switching mana color mechanic to keep me on my toes!

A very interesting technical achievement for such a short timespan with some cool mechanics in it. But it is a bit confusing and hard to play until you get the hang of it. Not the friendliest of UIs but I was impressed with it, due to how you build the game.

This must be the only Rust game in this jam. Impressive in itself. I did have a hard time playing it but got a bit into the game and could attack some enemies and ascend and descend stairs. You did have instructions on your git page which is great, but I think they should be on the itch page directly to make sure players see them. Its a bit of a hunt to get them now. The looking up and down made me disoriented, as well as the movement. Seems like it is a 2D game in the sense you can only turn around 180°. Would be nice with some sound as well.

Keep at it! Experimental guy ;)

Hm, this one is a bit to experimental for me. But you did your thing and I am sure your are proud of it, thats what counts. I did not hear any sound, so I can only judge the graphics and they are quite nice. I just envision more of an action game with those graphics and level design. Something fast moving, zooming through those structures. I though the whole time playing about old DOS games like Radix into the void or something. Well anyways, I could not wrap my head around the controls. I had to read the comments to understand the 180° instant turning. You should at least address this, as it would help with the gameplay.

Hey! Thank you for submitting this game! I had good fun with its unusual controls and style! The fact that you did this with Rust is really cool! Very well done!

Theme

I think it fits the endless theme and the cosmic horror pretty well. Good job there.

What I liked

• The concept of only having 2 directions horizontally was interesting to wrap the head around, but then it was really fun. I imagined being a 2D creature living only in 2D space ^^. It helped to transport the odd place and scenario.
• Climbing and having to watch your back while climbing was a very cool part of the game mechanics. It caused a good tension and also makes the game a bit of a player skill based game. Nicely done!
• The visuals transmit a feeling of being in a very strange place and underline the cosmic horror for me. Same goes for the enemies. You really hit this alien vibe very well.
• The overall challenge rate of this game. It was not super easy to learn and then even harder to master ^^, that puts up a good challenge and this again kept me playing and trying until I got the hang of it.

What I would wish for

• Some nice sound effects and a dangerous or brooding music loop or just some ambiance in the background would help to further transport the overall feeling of the game.
• I would love to have the different mana types on 1 and 2, or configurable, because this was the most challenging part for me. Climbing with Q and E was new for me and then having also to use the arrow keys to change the "ammo" and shoot with space, basically broke my weak mind a few times ^^. So a more intuitive way of shooting, or at least a key closer to WASD for changing the mana, would be nice (TAB for example). Alternatively two keys for firing each type, like  H and K as they are close to WASD.
• Actually I can imagine this game to be even more complex, by having to find the different abilities (mana types ...) first, or by having sort of stamina so one can only climb a certain height until one finds more stamina to "level up" :) - I know in the jam time such things are hard to get into the game, but maybe you plan a post jam version? Then I would love to have some more mechanics like this in the game.
• Ah and one more thing. I don't know how hard this would be in rust, but a red flashing and short screen shake or a similar thing to indicate a hit on yourself would be nice. Same for the enemies. Sometimes I did not knew if I had hit the enemy. A bit more hit feedback would be great!

Thanks again for having submitted this game! I'd love to see an updated version. 

Keep up the good work!

This was a unique take on the genre. The Light and Void magic reminded me of Ikaruga, and I thought it was a pretty clever twist on combat as you try to manage offensive and defensive strategies.

I have a soft spot for raycasters, so bonus points from me on that one :)

The controls took some getting used to. I was not expecting to turn 180 degrees, and coupled with instant step movement, it made it difficult to orient myself.

Great job!
