I absolutely adore this, I've not finished playing yet but I had to come and comment because everything is so polished and smooth, the details of the ground shifting to show what will be affected by abilities or where you can move, the little animation of the rats getting the trash out of the cans is sooo cute, in fact all of the animations are really cute.
The theme is so nice too, I love all my rodent warriors!
The tetris mechanic is super interesting too, its hard to choose between completing the lines and giving specific bonuses to different characters.
Speaking of characters the abilities are super fun too, pretty classic for a tactical rpg but just nicely done and they all feel good to use!
The undo button as well is very nice to see, I made a couple of mistakes that was just me being stupid so being able to go back and do it the way I actually wanted to was very nice.
Can't wait to see more of this, I am very excited!
