now i've finished the game.
i enjoyed it, but as i said: tools are useless. i had high disable and detect stats, but i still got hurt more disabling traps than running through them.
also, money doesnt do anything. why? and there is no increase of challenge, other than the map getting larger.
i enjoyed it, but needs some tweaking. for example, tower aim for the first ufo to come in their range. they then ignore ufos carrying sheeps that enter their range.
really nice! but its kinda strange to play a mario-game where you are "big mario" and still die when hit once! either make mario small or add power-up-mushroom!
