I think the TP combat system is pretty interesting. I have mixed feelings about the way you level up your skills. I think it's done relatively well, but trying to find the right mix of keeping TP high and buying skill upgrades started to feel tedious early on. I guess part of me wants a way to rest and replenish my health and TP all at once, even if it costs me to do so.
The art, level design, and music are all great!
