Flitter with a Gem

Flitter's Tip

Butterflies are your allies! Please don't eat us. Also, you will usually only see me every 10 min or so - it takes time to collect pearls and gems for you. They're so heavy. Do you have any pancakes? Or can you help me?

A Moment of Math

If you use Poison Cloud as your Smokescreen talent and you have Shadow Swarm active, you are missing out on a significant amount of damage. Almost 25 times the Shadow Swarm multiplier to be exact. Read the Smokescreen article for more.


Version 3.8.0 Available

You can now choose your Land of Reptiles Tier difficulty all the way back to Tier 1 if you wish instead of just the previous three. Abilities no longer turn off when you reset the game. There are new goodies in the Pearl Shop -- a 3x DPS boost, a double Abyss distance, and a new version of Tapper Crab. Unity Burst has replaced Temporal Flux, and it appears Killer Crab is gone.

Version 3.7.1 Available

Version 3.7.0 fixed an issue with resetting the game ad nauseum to get an Abby, as well as a (hopefully final) adjustment to the queen autobuy logic. They also made a regular Ecdysis start at 5% of your distance so everyone can enjoy the queen autobuy even if you don't have any ranks of JTP. With JTP you can go to 35% now total. 3.7.1 fixed a bug with ecdysis and Abby.

Version 3.6.0 Available

New version to start the Easter event. As with other events, there's a new skin for the AppX crab, some sets to purchase, and what has become a normal "prize tree" to get goodies as you collect the event butterfly every five minutes.

Also, the logic for Queen Autobuy seems to have been adjusted a bit -- hopefully no more queens sitting at level 1201.

Version 3.5.0 Available

Some changes to the early game as well as Quality of Life for the veterans available in 3.5. All reptiles, but especially those under 2000m now have less health than they had before, and you can unlock abilities sooner, including Ecdysis at 550 now instead of 650.

For vets, after you pass 10km at least once, you unlock the ability to auto-buy your queens on the next ecdysis. This can be toggled off in the options.

In Land of Reptiles you can now choose to go down to a lower Tier of difficulty in case you have advanced too far.

All good stuff.

Butterfly Arcade

We moved all of the silly mini-games into the Butterfly Arcade (under the Info menu) so they can be found easier. At the same time we added a new game specifically as a thank you to school sponsors: Benny For Hire. Ever have a desire to turn the tables and help the reptiles? Consider supporting the school.


A couple people have said we should have a Donate button. We do. Visit the Info menu to go to our information page where you will find an option for a one-time donation as well as becoming a Supporter through Patreon for recurring donations.
