FUN! My first playthrough was a blast! The combat is intuitive and extremely pleasant for its quick and forward UI. The art is amazing and Naka should be proud of his work! Regarding the balancing of items, it seems that defensive upgrades are a tad overtuned, I've won my only run just with just thorns and defending every turn (I couldn't help it, my love for reflect builds is unbearable).
There's a lot of potential for this game, keep striving for more content and i'm sure your game will be a hit!
Keep up the stupendous work and I HOPE PEBBLES IS SAFE AND SOUND!!
(Edit: If you two ever feel like localizing your game to PT-BR, I'm your guy HEHEHE)
