I've finally got to play it and I must say it's done very well. The opening you made is the best I've seen in a long time. I'm also interested to see how Nico will play a role. "Most guys would kill to be in your position right now!" That was great. ;P The whole "Koen" thing is starting to intrigue me as well.
The first puzzle kept me busy for a little as well. On top of that, the music you've chosen suits the situations very well and I love your sense of humour with some of the NPCs in the mining town! Arshes in a corner drunk and mumbling was great! Not to mention the man not too far from him scoffing at the elemental crystal cliche! Intriguing story and funny dialog. I haven't played through the entire demo but I'm liking it a lot so far. I'm really looking forward to seeing what you have in store for us! Please tell me that we get to play around with the battle system some?
EDIT:I just got to the battles! Wooo...Combo Shot requires button input to land a hit! I wonder if all of Koen's gun skills will be like that? I think I'ma be spending a little time in these caverns so I can buy some things I had seen before.
EDIT#2:I just finished the demo and man, that boss has some serious hp! The battles were awesome! Enemies on the map that respawn after a little time was a good idea. It removes the tediousness of random battles and allows the player to try and evade battles if they're just trying to get somewhere. The mine cart puzzle took a little bit of time but it was kinda fun riding around like that. I enjoyed the demo and can't wait to see the rest!
