This game really could use some sort of tutorial. The combat system is confusing and throws you into it without any sort of explanation. Players should really be eased into the concepts on display here. Starting out with 4 characters, 4 different hands and fighting 3 enemies it was overwhelming. The combat text moves quickly and is hard to follow, especially when you lack familiarity with the different cards.
The SPD chain thing was neat, and it felt like a system that could be fun to build strategies within, but without the knowledge to execute those strategies, it became very frustrating. I also seemed to have an over abundance of 0 cards and couldn't build a chain up very slowly.
I think there's something interesting here, but the barrier of entry was too high.
(I managed to crash the game twice, but I think the second time was my computer. The first time it crashed on the save screen. Didn't screenshot the error though. The second time it locked up in battle - I could hear sound effects registering but the image was not updating.)
Knowing this was made in VX Ace, I'm impressed by the amount of custom systems in this. Not a huge fan of the battle interface (feels cluttered) but the work that went into it is admirable. If you continue with this project, I'd love to check out another build with more time put into making it accessible to people outside the dev team.
