Ha! Another convert!
Genuinely, glad you enjoyed it though. And I'm always glad to see new people discovering it. Mind if I ask where you heard about the game?
"The mechanic of healing with energy outside of combat, while only being able to recover energy during combat, made me think strategically, and I liked that."
Excellent, and kudos to you for figuring that out on your own: a lot of people don't seem to realize you can heal out of combat with the ability instead of items and understandably struggle a bit. But I think it does add a nice bit of moderate challenge, because you have to think a little about which healing makes more sense in the moment, and have this little ritual of "bandaging up" after big fights, which I think pulls you in a little as a player.
And yes, I'd definitely recommend Gutter Trash if you enjoyed this. There's a LOT more to it, especially since it's been complete for a while now, and it's a bit more refined in terms of design too: this is literally the first game I ever made.
