How long have you been learning slick2d and have you ever encoutered its limitations witch you had to reprogram in java?
I've been coding in Slick2D for almost 2 years now. I have, but only recently. Since I've started making tutorials on Slick2D, I've noticed that their TiledMap class is more complex to use than it should be, so I just re-wrote my own map loader + renderer :). For my own projects I like to code everything with as little dependencies to slick2d as possible. I only use Sound, Music, Image, SpriteSheet, and BasicGame from Slick2D.
Do you plan on working with or starting a game company in the future, or just working solo?
I don't think GhostID will grow into an official company, but it will remain indie for now. :) Uhm I don't mind team work but honestly, programming gets hard when you work with others. Everyone has a different coding style and unless everyone works on separate parts of a project, it turns into a mess. If I work as a team, I would need artists, sound makers and musicians. x)
