Unfortunately my English is a bit bad, so sorry :D
Yes! Don't move, don't let the sprites follow the camera, don't let the sprites rotate, etc.
Just stand still and don't move.
I guess this is not possible, but maybe someone knows a solution...
There's another thing that I think would be cool, if you could make levels with grassy areas, which would fill up say the whole level. Don't just have bushes/sprites of small grasses appear!
Also, I'd support an "underwater" implementation, where even if you can't swim, you could at least shoot underwater monsters.
Plus there would be one more thing!
Doom also has an elevator or lift...
Please include it in the editor as a feature... I would like to add an elevator to my game! Using a ladder wouldn't be bad either.
Thank you! :)
