Have been doing Engine tinkering and also some progress on actual game side. Planning that the game will have 2 main modes: "adventure" and free "sandbox" mode.

Did also initial (and crappy looking) title menu where game mode is selected.

 

Started to develop a game based on my falling sand experiments. Let's see how it goes.  Also player character is a part of "sandbox", i.e. same rules apply also for particles that are part of player character.. More on this shortly. Meanwhile, here's a screenshot of player character in gamemode (horrible programmer's art again).
