This is very good. It took me a little to understand the core mechanic but I like it a lot! It's very cute and the little sound and particle effects add a lot to the game. Great work!

It's a simple, but tricky game.  Had more of a puzzle feel to it.  It was difficult to predict their movement.  Going after them felt like a gamble.  It wasn't clear what the win condition was.  Do you have to absorb all the crawlers?

It's a good framework.  A little more clarity would help.  Some background music would also have been welcome.

* very impressed you did this in two days!

* I think it works well as an endless miner, but I wish I could "win"

* I like the self balancing aspect of "as you get more empty space, enemies automatically carve more tiles"

* confused how to kill the + and x's. is the only way to use a rune? but their body is not positioned at the center?

* It wasn't clear why I died. I guess that the tile I was moving into was about to get crushed?

* I like the mana animation! but it made it hard to see at a glance how much mana I actually had

* I didn't understand how much mana a rune costs. Is it always 1? sometimes it looked like 2

* It took a bit of time to understand what the runes did. I didn't know what the symbols meant, nor that you carve a path to your target. One idea is to temporarily show two of you: one at the original position and one at the current cursor. And as you're moving the cursor, drawing the line automatically. When you hit a symbol, also draw the shape it will carve out

* I wish that the single dot enemies stayed on the map; sometimes they just disappear and the effort to capture them is lost

Here's my playthrough: 

What a novel and tight design! Simple, beautiful, and deep.

I've had the opportunity to test this game on stream alongside its creator. It has been a perfect experience.

I will always positively value any original idea that is executed, and this game has managed to apply a new idea ingeniously and swiftly. I also value the use of a restrictive color palette, only 4, and minimalism taken to its highest expression.

However, I do miss a bit of UI indicating the score or turns, just to nitpick a bit. The particle effects add a professional touch to the overall finish of the game, and it has been fun to try out the different patterns of the runes.

I wish I had been more skillful to achieve a better score, but as we all know, roguelikes are complex games where we die a lot and often, haha. Technically, I find no shortcomings, and I like the minimalist design! If you decide to finish the project, it would be nice to add a hardcoded mini tutorial showing the runes or a help window showing the in-game controls.

In conclusion; I really liked the game, and the idea is truly original. I have to congratulate you on your work, it's amazing.

Very nice, well polished game! Great job!
