Here's my thoughts after beating the tutorial:
It took me roughly 20-30 minutes to beat the tutorial, and that should've been the length of the whole game. That would have given much more time to add substance to game, because right now I am not compelled whatsoever to finish it.
However, I did see some good ideas in there. I like how the progression works, with items increasing stats, exp unlocking moves, and the lack of levelling up. The combat system is great and it manages to create deeper strategy early on.
Overall I'd rate it like a 5/10 game. Any substance this game has is spread way too thin, but the gameplay has really good potential.
