12 normal opponents. 5 bosses. It can take time to master the technique. The first round of opponents are supposed to be easy so you can get used to it, but it gets harder with each division. You can also put in the passwords to practice on each arm wrestler. Worse comes to worst you can put on the super strength password if your fingers aren’t able to go that fast.
Make sure you’re successfully training too, otherwise you won’t level up and it’ll be harder as the game goes on.
I intended this game to be “nes hard” and in the description of the game it’s says it is. I do have to other games. Plummet Challenge Game which is super easy because you die every level, but it’s all about how many points you get before you die.. and Carpet Shark which also starts off easy and gets harder with which level.
