Nice game concept; graphics aren't bad. However, I don't think your troop function or retry function works. And your next wave menu appears on a layer below the player's towers. I would also like to see shortcuts implemented, especially for the pause function. Try putting menus on the right side of the screen, for aesthetic purposes. All in all, test your game for some easy to catch bugs and you'll get a much better outcome. Nice music. Keep it up.
... I though it was too easy... Innovative concept but doesn't allow much elaboration. Simple trace algorithms can be used to figure out the combination in less than half a minute. After that it's just trial and error to get the timings. Still, a solid game though. Love the editor.
yes, customization is a good idea. i would like a key combination that does not require me to put my hand in an awkward position as I can never remember any of the shortcuts.
i really think the letter shortcuts could be better. i mean seriously, BTCMWG? try keys that are next to each other instead of referring to the name of the action.
