Interesting so far. Not sure if you are able to escape the tunnel yet, pretty sure i cleared it but i may have missed something. I do have some criticism. I'm not really sure what the ENTIRE story is, mainly because i found the beginning info dump just not really all that entertaining. There are some grammar errors in it, but overall not horrible. Outside of that i think slowing down your first combat when you are learning how to fight would be helpful, just so you really have a chance to figure it out, though, i managed to pick it up pretty quickly so maybe not.
Overall awesome start! Keep it up, i'll be sure to check in on it regularly that's for sure.
