I have an idea for a block pusher game:
mergemount/craftmount/fusecove/etc.
gimmick: on the right side of the screen theres the gray spot thing that's in this game, and in some levels there'll be an uh thing that shows tileA+tileB=tileC, and if you push tile A into tile B, it would destroy both but make tile C
OTHER THINGS FOR THE GAME:
alternative colors: in some levels, tiles will be a different color, and the crafting recipies require the specific color for each block (ex. if white multipush block+white wall is base recipe red multipush block and white wall wont work, they'll just act like their normal counterparts) also, in the earlier levels you could use black tiles to trick the player into thinking that black tiles don't merge with anything, then use white tile+black tile=other tile. also, inverse tiles actually cant merge with anything, and the ? could be used to show anything or a random result or a block could merge with anything, etc.
multicrafting: some recipes could make/require multiple tiles, (ex. wallx2+multipush block=button- wall would eat first multipush block then make a button after eating a second one. ex2. wall+multipush=2xmultipush- it would make 2 multipush blocks [duh] but push the second one in the direction that you push it in)
epic crossover: some recipies could have the covejank symbols on them that would make them move like the blocks from covejank (ex. right arrow would move the resulting item one tile forward from where you pushed it from)
your welcome :)
