So, i said i wouldn’t do normals, but i spent a good 4 hours brainstorming ideas this morning, and ended up landing something really simple and effective. (so now i am doing normals xD)
The basic concept is based on an adaptation of Nokia’s Snake game, and came to me when looking at a rubix cube, so its based on a grid system!
The player has 10 seconds “until death” (name of the game) and must pickup energy to keep your space ship running. Lest ye run out, and explode dramatically.
Similar to snake, upon picking up some energy, a new energy pickup will spawn somewhere on the grid. Over time however, walls will begin to raise around the field slowly creating a maze. There are further designs that add extra complexity to the simple task of surviving and gaining a top score, but for now those mechanics are my base to create over the 48 hours.
1) Player energy mechanics – UI Timer, the pickup, death explosion.
2) Player Controller – WASD / Analogue stick for movement, mouse and click / Analogue Stick 2 for shooting (eventual design ideas for turrets)
3) Random Walls from array of preset walls raise over time.
Here are some prog shots:

Clearly the wall and floor, there are 6 variations for the floor with the bay doors rotated and vent shapes altered, they will open, the pickup will raise out, and it will close, similarly, later on in development turrets will raise from them, creating a secondary obstacle.
Next is creation of the walls some dangerous variation of the walls and floors (laaaaaser Wallllls etc) ^_^
then dDo license ftw!
Im going to aim for a sanctum style colour scheme, something soft and bright! break time with Dota for now!
