Pros: Interesting characters. Easy battle system.
Cons (such as they are): A little light on the backstory and plot. Leaves a lot of questions unanswered.
Overall: I like it. You've got a strong storytelling ability, so play to that strength as you continue with your Kickstarter project. While I would have liked for the game to delve even further into the characters' stories and the story of the world you've created, this is obviously more of a playable teaser trailer for your project, so it's going to be small. I just hope that project doesn't neglect these characters because they deserve to be fleshed out. You've left me wanting to know more, which is a good thing.
Gameplay Tips: You can probably beat the game with any combination of character classes. I went with Cinnacat as a Wizard, Dawncaller as a Guardian, Lorena as a Sorceress, Trickfoot as a Thief, and Warren as a Hunter. These largely line up with the character descriptions in the class selection screens. Trickfoot is the exception. The game explicitly states that he's a Healer, but make him a Thief. Being able to Steal food and gold is a huge help throughout the game.
Speaking of food, it is your way of getting free healing and energy restoration for the entire party, so it is essential to make sure you have some on you at all times. Get as much food as you can. Aside from defeating enemies, Stealing is the only way, which is why the skill is so important to have. You use your food when the party rests. While resting, you are first given the option to level up your characters by spending gold, which is the other reason why Steal is such a valuable skill. Once you exit the level up screen, you will be presented with a screen on which you have two options: Search and Rest. If you Search, you have a random chance of all party members being fully healed. If you Rest, you have a random chance of all party members recovering all their energy (the game says that you also have a random chance of being ambushed, but I never encountered an ambush, so the chance must be very low). Make sure to do both whenever you rest.
You'll be given the option to rest after each fight. Because you can recover all your Health and Energy between fights, don't hesitate to go all-out with your attacks. If you followed my recommendations and made Cinnacat a Wizard and Lorena a Sorceress, then you will have 2 Bomb attacks every round. These attacks are very handy in the late game. They consume a lot of energy but do more damage than any other attack in the game, which is great against the late-game's high hitpoint foes.
Finally, don't forget to level up.
