A surprisingly rewarding game with hidden content and no ads

First off, as you can see in the picture, there's hidden content up to level 400. The efficiency is best around level 200, but I plan to milk it till the end >> In that case, up to 400 isn't too bad either. Later on, there will be some walls, but if you're playing, the key is to push through as much as possible in one go when the time is right. There are sections that are tough without helpful items. Every time you clear a 100-level milestone (100, 200, 300), you get a reward. Grab that and push about 50 levels further. For reference, the second picture shows a permanent event (the island flag on the left). You're playing against bots, so don't stress about the time limit. Play comfortably. Usually, you get 1st place. Just tap on all the events. The last picture shows 4 energy bars at the bottom. This means you have 4 energy units available, and you need 3 units to use the skill that looks like a battery. Each pet has different skills, but if you're playing without spending money, just diligently raise and level up the cat. Around level 300, you'll unlock various skills, and by leveling up the cat's head, you'll eventually have 12 energy bars. ☆Always make sure to utilize your pet's skills every round. They get fully recharged when you enter the next round anyway.
