It's getting tough at level 15...

Looks like you've hit the level 15 wall. That 50,000 coin opportunity is too good to pass up, so hang in there for the remaining 15 days. It's a totally worthwhile challenge, hmm!

I'll take it easy and play at my own pace lol

You worked hard haha

If you've used up all your acceleration items by level 15, it must be really tight and you'd be worried. You're only 3 levels away from your goal, so if the reward is certain, it might be worth pushing for it, but if you're too tired, taking it slow and enjoying the game is also a good option!

If you play non-stop, it takes about 2 weeks to get from the start to level 18. If you're enjoying the game, I think it's worth it.

100코인주는거면 할만하긴함 15일이나남았고 전 코인이아니라 8천젬받음 ㅋㅋㅋㅋ 왠만하면 투자해볼만함

Even if you use up all the items, they'll replenish as you do other things. You can also use diamonds, so it's definitely possible. I'm already level 17 just by doing time quests whenever they reset and the accept button appears. It's totally doable!

I'm only doing this to get 24 Hidden, but I regret it. It feels like a waste to give up, but also a waste of time to keep going... I'm getting addicted, keep logging in and playing for an hour ㅠㅠ

You worked hard! Keep it up!
