The game has a lot of great points going for it. It really put me in mind of jRPGs from the early Playstation 1 and 2, and I really liked the overall feel of the game. The characterisation is a bit bland at points, however, and can seem a little rushed. Understandable that this is a prototype and not the full game, so it doesn't take the time it normally would to let the characters get to know each other and fill in the NPCs and world with more than just a quick splash of identity. Something to look forward to in the future, though.
I do wish the skill learning were a bit less 'my first skill tree' in visual - it lets down the rest of the game. I'm also not a big fan of the way you choose which character to upgrade during it. It's one of the biggest issues I have with the game for as much as I played it. I think it'd work as a menu styled thing than just 'floating in space with staaaars'. The aesthetic is a bit weird.
That said, the sound, gameplay and overall charm the game exudes makes it one of the few I've given 5 stars. I really enjoyed this game. Great job!
