It's so hard to balance things out

10 days in means you're still getting the hang of it. The key is to upgrade your gear evenly across the board, not focusing too much on one specific area. If you're F2P, you need to be extra careful with resource allocation to maintain balance.

Sometimes you can balance things out by choosing the stat boosts that are lacking in the exercise category. You can also do events that raise that stat.

Seems like it takes quite a while to get into this game, huh?

This is the screen of my character that I've been raising for 10 days without spending any money. It's tough to raise them because they come out randomly.

It's hard to balance things since the training bag is random ㅜㅜ

I'm also filling up whatever I'm most lacking in at the moment.

Can't be helped ㅜㅜ

Since it's random, stat imbalance is unavoidable. If your training ground is activated, choose low stats.

All gadgets disproportionately boost stats that are already high. (e.g., if you get stuck on a climbing section during a race, only boost climbing stats...) As you continue the race, the stats will naturally rebalance. Since the stats themselves are random, when you get stat choices from bags or boxes, just pick the lower stats.
