Fun until you reach the higher levels

When I started playing in 2012, ZooKeeper was a lot of fun and very entertaining, with just enough challenge to keep me playing and working to reach the next level. Presently I am at level 141... and it stopped being fun a long time ago. It takes me nearly 3 weeks to hit the next level. I wanted to reach level 150 and get that last door unlocked but this game has turned into a long, dull slog and its time (long overdue) to quit. I recommend playing while its fun, dont spend much money at the shop, and then quit when you get sick of it.
