A step by step WIP of a storyboard screen from the upcoming game Sub Terra Draconis is shown in the below video.

Sub Terra Draconis follows a little hatchling dragon as he grows into a big dragon. At various stages of the game he will gain abilities such as breathing fire, which will affect how the puzzles in the levels are to be solved.

Sub Terra Draconis is still listed on Steam Greenlight and needs your help! Please vote for it by using the below link or Crystalshard.net. Thanks for your support!

Hi Radiant,

Thanks for the answer ; I gave a glance at the gameplay video and yes, it now looks more puzzle than speed play that's great. Thanks !
Hope beside Steam you also release it on a DRM-free, internet-free plateform such as ich.io, GOG or else.

Hi Franbelle,

We'll certainly be releasing the game on Itch.io, and also wherever else we can get it on :)

Hi Franbelle!

Yes, Sub Terra Draconis will incorporate elements from ST2 as well. We're looking at picking the most interesting elements from both games, so elements that are rarely used will possibly be left out. Draconis follows the same design as ST1/ST2, meaning there are substantially more different kinds of game objects than in BD or Supaplex, and the game overall is more a thinking game. I hope that answers your question!

By the way, what happened to SubTerra II which was available on your website some years ago ? Has it been incorporated into the newest SuTerra version ?

Watching the Steam greenlight video it seems to me that the upcoming version is bending more towards Boulderdash or even Supaplex, while the old SubTerra was more on the puzzle side. I mean, action and speed versus brain thinking.
Is that true or a mere distortion of reality due to the low number of levels in the video ?
If this is true I will regret it ; AFAIAC I beleive the strenght of SubTerra was precisly a better balance than Boulderdash.
