Without a mouse? Ouch!
Left ring on the "1", left middle on the "2", left index on the "W" and "S" (back-and-forth), thumb on the "Space". Right hand directional (until you catch a mouse).
Yeah, without a mouse is ouch in more ways than one... my poor right hand tends to hurt after I've been on the computer for a while.
Also many thanks for the advice, between what you gave me and what the hubby was able to do (better twitch reflexes) I finally finished the tower. Now all I have to do is Maxios' room of jumping (that mouse better come soon)
I wish I could figure out a way to jury rig one of my wireless xbox360 controllers to play these parts but I have no idea where to begin.
