Very Nice, I played for about an hour as well.
I built a fire based Arbiter/Priest/Paladin character with some frost resistance gear, and it was a nice experience. I did end up dying however, because I was relying upon the "Glory" buff to survive, and it expired in the midst of combat.
- I enjoyed the skill tree. I am overall a fan of large skill trees with dependancies such as yours. I would encourage something like a "Minimap" for it, or perhaps an option to zoom out and then back in on it, as I initially got a bit lost and confused before I noticed the arrows linking between classes. I'm quite fond of the skill tree in path of exile, you might benefit from having a look at how they link and group skills visually.
- My bags were frequently full, I returned to the start of the game part way through to sell everything once. It was a tragedy to pass up so much treasure.
- Do you plan on adding equipment sprites? This might make the enemy types more readable, and it might be interesting to have a more visual sense of what classes you're going up against. Having their class names match the class names in the skill tree might be interesting as well, as it seemed like they might have been drawing from the same pool of skills as the player.
Thanks for making this, I enjoyed it.
