could be a good game but in the way the collision detection is just.... too bad for my taste.
example:
you have a block and a block underneath it and beneath that a wall.
you go to the bottom block, move left and up.
then with that block going down and right should slide it beneath that upper block again, right?
ince it totally fit in there before?
WRONG!
Or the same issue with corners in general.
soemtimes the corners perfectly touch of 2 blocks, yet you cant move them past each other.
but also cant walk from one to the other.
but you better not dare and STAND on the corner of a block and move said block then!
you might be considered to be part of the diagonally adjacent block when moving away.
yet are completely stuck, you cant move anymore.
and trying to move the blocks back into the position where they are placed diagonally?
well, now they dont eve touch.
cause upper left is one block, then there is you as an object and then the lower right block.
and you stuck in the void as some immovable object that now belongs to neither block and can only jsut restart the level :-)
yeah, some weird quirks there, just saying :-D
