Version 0.20
Sorry for the lack of updates, but it is not the engine's fault.
I purchased a copy of Terraria 3 for my iPad and got hooked for a couple of months, the rest of my time was boosting the quality of the Blender scenes I then render out again in Cycles. Later, a very neat Sonic fangame (Sonic Robo Blast 2) saw a new version released and I played that a bit. Not much time for game making.
The new version boosts the level count to 18, along with some fixes and polish. The issue with the esc key terminating the game instead of going back is resolved, and the elevator button text is now nicely centered. There's also an unlocked feature after 15 levels where you can leave "breadcrumbs" to mark places you've been in, something that is needed with levels becoming bigger and tougher.
