Linux build works fine, although on 21:9 aspect ratio the game cuts the top and bottom of the screen, so I was unable to read what the game text was saying. I suspect, it's like that on all platform builds. It's best to make sure game scales properly across different aspect ratios, but for a jam you can also simply enforce 16:9.

Concept is interesting and could use more meat. I think some random variation would be nice, since they always seem to attack the sword guy. For example, you could add some enrage ability that would highlight the person they would attack next, but also deal double damage the next turn. Maybe they could highlight several characters they would attack (some AoE attack), and player has to choose who to defend. If you implement AoE attack, healer could use a weaker version of healing that heals all player-controlled characters. You can also surprise player with choice slider having different animation dynamics: different speed, tweening with easing in vs easing out vs easing on both ends. Maybe choice zones could be varied slightly for added difficulty.
Also, I think it would be nice to have a story explanation of why player needs them "down" instead of "dead". Maybe, a wizard hired him to get some goblins captive for wicked experiments ;) Could be a simple story text in the beginning, or a small cutscene.
Good job and thank you for different platform builds!
EDIT: Forgot to mention, that I needed to add executable bit for it to launch on Linux.
