hi, thank you for playing and the feedback! Most of the problems you mentioned have been noticed and fixed in a new update i plan to put out after the voting duraion ends! I'm also planning for QoLs and a new mechanic to make the game more fun as well! Please look foward to it~
For the mechanics you mentioned, i will try to convey them better in the updated version, but i'll also put it here in case you want to know: footwork increases your strike, berserk, defend and support actions' success and remoteness increases your shoot, aim shot and recover actions success. Success also increases your damage by a small amount as well. actions that "aim for the closest target" mean they aim for the characters whose meter is the most filled up at the time.
If you like this mechanic, i do recommend checking out the franchise "Medarot", which this game's mechanic was largely inspired by!
