The concept is really neat. It sets a random stat to 1, and forces you to work around it, and you only get one turn each battle to win. The problem is that the game sort of gives you everything and expects you to do it. You only get one chance to see the opponent's stats and memorize them at the start of the battle. And without any knowledge of how the calculations work, the game does become trial and error until you've played the game plenty of times in order to grasp how much damage you would deal, and because you only get one turn before you auto die, you end up dying a lot. At least at the start.
After getting a grasp of the system, and all the moves available. The game does become pretty fun. Most of the strategy becomes hitting the right enemies with physical or magical moves correctly, once you figure this out the game is smooth sailing.
Stat changing moves and healing feels a little pointless because you only have one turn. All runs are almost the same, except when attack or magic attack is decreased as these stats are what matter the most.
I actually don't mind the unfair RNG deaths in this game, sometimes it wipes out one character, and you have to find a way to finish the battle without using them, which can actually be very interesting.
Beating the game is however very satisfying, especially with a nice credits ending. Not many jam games have a bit of a story like this, it was actually very refreshing to play through, I really enjoyed it! Perhaps the game design aspect of it is weak with flaws in many areas, other than that it's very enjoyable, fits the theme, and is very original. It would be great to see this fleshed out (perhaps without the one turn limit as this is what's limiting the available strategies) after the jam is over :)
