definitely based off of maplestory -- haha. it's pretty decent. it could use some physics tweaks, the "out of range" seems a tad pointless, but all in all it's pretty enjoyable
picross games are fun, but the one thing hurting it is a create-a-puzzle mode, where you can submit and people can try them and solve them, and then vote on them.
the game is ok. the idea is good but in the grand scheme of things, it's pretty broken. ie, once you get good units, the game slows down a lot because you're just destroying everything in your path which doesn't give you as much exp. there's also the aiming and the camera, which i'm sure you already know about.
Good idea, bad execution. The collision detection is horrible, and even though that's it's one big flaw, it's big enough for me to keep me from playing past the first couple of levels.
