Hey xicx,
I just completed a run and all in all it's I think it's good. There's a few things that aren't clear to me, like what's the purpose of money and the big gray skeleton, but I'm assuming they're still works in progress.
What hit me right as I started is that the field of view is extremely small and the huge UI covers a lot of it! I was constantly shooting in front of me while I was walking, because I never knew if an enemy was going to jump on me. The enemies are also similarly colored to the ground tiles, so they're hard to see even on screen. I never used the dash for these reasons; it just seemed suicidal. Additionally, I got lost a few times even though the map is not that big. I just couldn't see where the paths lead to and my memory is mediocre.
