I've been playing this game for a few months. There isn't a lot to do, but that's the point. Check back a few times a day, get more XP to unlock more stuff.

You can unlock pets which boost your XP gain and lower the button cooldowns. The first few weeks have really slow progression until you prestige and build up XP boost. The first 2 prestige buttons are unlocked at levels 100 and 200.

Mid-game is a lot more fun once you can speed up the gameplay loop with about a 20-30 XPBoost.

It has a semi-active dev, and it's a fun progression with a simple concept. So start checking back and see those numbers go up!
