Okay so I made this and sent it to a few people and I may as well just post it bc I don't want everyone to cry and get one of the best comps removed tbh because wbk that happens all the time.
Weightlifting:
You'll notice at the start the colours of the dumbells are bronze. These will change to silver & gold throughout.
Bronze:
At the start of the competition, literally do not press anything. Focus on the ball in the middle and until it starts moving, very subtly tap the arrow key of the opposite direction (only do this once it's quite clearly moving)
You should be able to stay in the middle for quite a while, at least until silver.
Silver:
The ball will start to move more but is still pretty manageable, you'll have to tap quicker but still aim to keep it in the middle as much as possible. The only way of learning how much you need to tap is just by playing and learning when you need to adjust
Gold:
This is where it'll get harder, the ball will move a lot faster and you'll have to hold down your keys in the opposite direction when it does. Hold them, but not for too long, as you see your ball start to roll towards the other side there will be a lot of "weight" to it, so then start moving in the opposite direction before it gets too late and drops off. Again, a learning curve, but just picture it not being able to "climb" back up when its tipped all the way to the other side and you need to move it back before it gets to that point.
Keep it in the middle as much as possible obviously, particularly at the start so your score can be higher.
This isn't obviously going to work for everyone. There are better players at Weightlifting than me, I tend to get between 10-12k and this works for me.
style, CarltonRS, Dream, NaughtyNacho and several others, including the Hall of Fame score better than me, so they might be able to advise more. This is just what I do.
