Hello!
I'm really glad that you loved playing Sliding Hero, it means a lot.
About the enemies not popping out that much: yeah, in some rooms there may be some issues in reading them. I will probably add a little glow or some other shader effect to make them stand out a bit more, and probably add an accessibility setting to really make them visible.
Regarding the bug, it's an issue with the WebGL version: I did a new version a couple of days ago in a rush and forgot to flag a Cinemachine Camera as off, so now each time you reload the game it makes that particular one the priority. This issue is not present in the executable version.
Thanks again for playing!
