Not yet; I'm making core systems first and will then hand craft levels for sustained play.
The plan is to make more combat elements, in the form of more enemies, weapons for the player, and various additions on top. I have various movement related mechanics ready made, so now I'll be focusing on enemies and weapons. Once I have a good variety, I can plan out stages with real content and get people playing the core loop with real features in, as opposed to just having a repeat of basics.
