Due to sporadic internet, if at all, here's basically a summary of the first two days.
I managed good headway with the engine and a quite nifty editor (thanks to my NIH syndrome sponsored GUI library). The used themes will be castles and assassination.
Infiltrate the castle and assassinate your targets without being seen. As a good assassin you can climb 3d block based castles to avoid footways; better than Lara And since you're there, why not bag a few valuable trinkets as well?
Since there's two days in this entry here's a second glimpse (showing a probable tutorial level inside the editor)
Looks great! Kinda reminds me of Fez.
I always enjoy playing your entries so I'm looking forward to this one!
