really hard game, even when I find a groove suddenly it will throw something mind boggling at me. I did play for 3 hours last night, by far the longest I have played with my guitar in one session.
There is a "guitarcade" that I like a lot. For example, one mini game is that cowboys are coming in to the saloon and you have to keep them from getting to the bar. They walk down strings and you have to pluck the right string to shoot them. I played that for a good 30 minutes and I am sure it will help with finger picking and landing on the right strings over time.
Also there is one where zombies are attaching you and you have to play a chord to kill them. It is challenging and fun and likely improves my hand movement and strength. I dont know if I am actually learning those chords but over time I am sure if I see F5 I will know exactly how to play it now so maybe I am.
I also played a game called scale warriors where bad guys get on the scale and you have to strum the right chord they are on and then say they are on E on 2nd fret and you hit them, they go to fret 5, hit them again they go back. Then bosses will go from fret 2 E to fret 5 E to fret 2 A, fret 5 A and etc. Seems like a good learning tool too, just will take time.
The song playing is very difficult I found so far compared to how I have been learning songs on my own but maybe over time that will get easier. I do think the minigames will greatly improve my strumming, picking and fret movement/finger placement though.
My fingers hurt but nowhere near as bad as they used to, think I am finally building some callus.
I also learned that electric is a lot different as if I puish too hard on me electric strings, I dont get the right sound. I kept trying to play E on the first fret and it would never register until I googled it and found out I was simply pushing too hard.
Making it quick and easy to jump in really made a huge difference in how often I practice and has helped me improve much faster than when it was 10 minutes to set everything up.
