Incredible game! All aspects are super polished for a game jam, especially the art and sound. The title screen gives an especially strong "wow" effect. The upgrade minigame is also a nice touch. I also love tactics game.
Even though it's awesome, I still think some details that could be improved. I'll try to mention new things I haven't already seen in the comments :
- (Already mentioned by VikFro but its my major issue) the game is a too easy. So much that the upgrade system can be ignored all together without feeling you're missing on something. There is also a power imbalance between characters: S0R3114 can just slash through waves of enemies, while F1STON is stuck walking slowly, and the "specializations" of weaker character don't counterbalance this enough (eg I don't feel there is a strong use for pushing things).
- Starting out with all characters felt a little overwhelming. I feel like starting with a small mission with 2~3 characters would have been a good preliminary step.
- Give visual feedback why you can't do an action (e.g. shake the depleted movement / action / healing bars in the top UI corresponding to the action). It's would be especially useful in the first levels when you start to get the hang of the game, and can't exactly understand why you are stopped. I was confused by the healing charges bar for example.
- The upgrade mini-game is a little hidden. The "edit orphan layout" button could be (way) bigger, a different color / style, or something to make it stand out more.
- Small bugs: It seems the "damage boost" actually increase the healing charges, and M0TH3R has errors on her info panel can't be healed.
I'm being very picky because I believe its more useful feedback then just praise, but its truly very good, and I gave it a very high rating. ^^ I look forward to seeing your next games.
