I love this game

but haven't gotten to level 5 yet. I'm a lefty and for all the years I've been using a mouse in my work and at home, I always used it as a right-handed person (kinda). I did not change the mouse orientation and used my index finger for both right and left clicks, switching between the two buttons with one finger. This game has shown me the error of my ways!
After trying several times to reach Vanquisher in all levels, I gave up and started using two fingers left-handed but with the mouse still oriented for a righty. Retraining my brain to left-click with my middle finger and right-click with my index has been a challenge to say the least.
When that didn't work, I gave up and changed the mouse to be oriented for a lefty. I've managed to get to Vanquisher in all games for the first two puzzle sets. I'm working on Davy Jones's Locker now. Still retraining my brain but it is getting a little easier. Having senior moments doesn't help much, tho.
