The field of vision is too small. In order to stay far enough away to dodge attacks, you have to be too far away to see the enemies. Half the time I find myself staying at one end of the zone and firing randomly across the zone trying to hit things.
If you zoom in, you can see the slope on the edges of the line segment. Useful if you're having trouble distinguishing between a straight slope and a round edge.
I like that the walkthrough solution for the last stage involved a little dancing around, just like my solution! The walkthrough shows it in 25 Commands and 265 Calls, and I don't understand why it involves 2 consecutive uses of the light command. I can't figure out what, if anything, that does. My solution was only 20 Commands and 200 Calls:
SPOILER
MAIN: Right, Jump, Left, F1
FUNCTION 1: Right(orange), F2, F2, Left(orange), Jump, Light(purple), Jump, F1
FUNCTION 2: Light, Jump, Walk(purple), Left, Light, Jump, Walk(purple), Left
Quite random toward the end, and I had to cross my fingers, but it got the job done!
Great game! I love the subtle Simpsons and Princess Bride references in the characters' names. I wasn't sure if Lenny was supposed to be Lenny from The Simpsons until I also saw Carl. Also, what's the "T" stand for in T.O.U.S.?
It's Picross with the added element of additional colors. I really like Picross, and I LOVE adding elements to things! I also like how the author so obviously played World of Warcraft.
I love the music. Did you make it for this game, or is it from somewhere? Sorry if the question was answered already, but I didn't see an answer in the first couple pages of comments or in any in-game credits.
