Great logic, you got potential :) Get some guy to do the art and you could do great things. Btw you used Shiwari chips to do grid movement or you buid it your own?
This is my brother’s level and it has some great logic in it. The grid logic was built from the scratch by him and all objects and monsters in the level act as in the great c64 classic, Boulder Dash. He will publish additional levels soon so if you like this level, you may want to visit his earth in the upcoming weeks.
