Amazing simple mouse game :) I love the sound of chickens for mice :D

It left me wanting more... In a really good way :)  Love the rats and their personalities.  I'm not sure I'll ever get bored of watching them float up the screen :)  If you introduced a few new mechanics, this would be on its way to bein a commercial game :)  well done!

Fun clicker game... and very addictive :p

How many rats does it take to change a lightbulb ? 

well you need 2 rats to make a farmer rat 2 farmer rats to make a miner rat...

Ok silly joke aside, i really dig the little rat sprites with the various hats, so fun to see the results fusions get you, especially when you discover that you can have multiple pairs up at any time to make mass evolutions XD

I was really curious to see all the evolutions.

Simple but very fun entry, good job :)

Merging rats into different rats was fun and seeing what new rat will evolve loved the idea too defo see this going somewhere like the rats could be used for something to give another reason for wanting that Epic rat

Adorable!! Makes me want a pet rat NOW!!!!

That aside, the game looks great and it's fun to see the rats evolve. Just wish I could progress through it faster

I genuinely probably spent way more time on this than i should have... the rats were TOO cute!!

Nice game, and reminded me of idle clicker games. Exponential growth of milestones were a bit on the tough side. Using a tech tree or/and power ups, and even having your miner rats work on progression could make this a really promissing game. 

These rats needs a game to go with them! They're so cute.

I never managed to get to the "Pope Rat", because the exponential scaling was a bit much to take. This is a type of scaling that almost never works, in any game, except if you really delve into it and explore different sense of scales (Universal Paperclip, Cookieclicker) or use it as the sole mechanic (2048).

Without any deviation to that "doubling", you leave no room for player expectation. If the player knows that the next 2 minutes is going to be exactly like the last 2 minutes, just with even more clicks, it's hard to keep them motivated. They need something to optimize or some agency in the direction the game takes, instead of feeling like they're only making the frames go by.

Examples of what you could have done to achieve this is variation to the "tech tree" of rats, like having to combine varying number of certain kinds of rat. Think "Little Alchemist", simple and addictive to find combinations.

Since you also had the ability to pick up and relocate rats, a Lemmings style mechanic would be right at home. You could have the rats walk around and getting into places they shouldn't, like in the combinator when you're trying to combine two other rats, so you need to drag them away. A hamster wheel with limited space to place them in, for example. The player would have to need to balance how many rats / how productive / how fast they want to progress against how many rats they can keep track of.
