For a first RPG, it's reptty good, but I have a fwe suggestions.
Perhaps limit the amount of Exploding Arrows you can have out at a time, or have them only able to come out when you're very close to an enemy. I sort of abused the ability to kill all the gaurds and the last mage. Once I got them, I never really had to go back and heal much.
At the end, I would writea little thing explaining what happens, so you don't suddenly win. People like endings... well, more that people don't like maps without endings, lol
The Adolescent Dragon (hydralisk) is too weak. Hydralisks do half damage to marines, so the archer has a huge advantage.
The Child Dragon (drone), never attacks, so it's free EXP. I would make them attack by having them patrol or something, or make change them to a different unit.
The Crsytal that heals you doesn't show up on the minimap when you leave that area. Maybe you could get vision there, or have a beacon or something there.
I would add a little sound, atleast for when you level up or intro music or somehing, just something short and quick.
Other than that I thought it was pretty neat. I beat it one player (the Exploding Arrows can be abused a bit =\ lol),. I liked how the amount of EXP you needed to grow a level got bigger, a lot of RPGs don't have that. ALso, the abilities were simple to use, and it was neat that you had to save up to get them.
Anyways, it was pretty neat, and I hope this stuff helped at least a bit,
