im trying to imagine these tiles used to make walls in a shooter since they don't seem to have any structure to them.
they look like rocks at the bottom that would just fall apart if not supported.
seems more appropriate to make some structural rocks with coral or something along the lines of Xenon 2:
OMG! this was my favorite game as a little kid, I never managed to find it as I didn't know its name, so thanks a million :
My idea for the game is having the player being able to scroll sideways indefinitely until he hits the a rock wall while having rock obstacles shapes and/or mazes in the middle to keep it interesting,(it works well in my head but I guess I'll just have to see how it works ingame)
I'm currently working on more edge shapes. If you have any input on the idea please let me know .
