The Blips and Chitz tickets can be purchased with actual cash, but you always seem to get 1 after the council battles.
As for the game, it's pretty...bad, IMO. XP rates are super low so it takes ages to level up Morty's, and while you can just "combine" some of them in the daycare, you can only do it once or twice and that's it, then you're stuck leveling again. Prices for items seem super high compared to the money you get from battles, too, especially in the beginning when you have one or two Morty's and you need items most. The actual levels are also super repetitive, and could benefit from a "pit stop" type deal where you can heal up all your Morty's. Moves have such low AP that you just run out of attacks after two or three battles, so you have to either continually switch between multiple Morty's to keep a good amount of AP for the "boss Ricks", or craft/purchase more Plutonic Rocks...which is annoyingly inconvenient to do, because you don't get enough money, or crafting supplies to make all that much during levels.
I do like all the Morty's though, they pulled out a lot of neat little ideas and the art for them are pretty great. I used all my mega seeds on my normal Morty and made him OP as hell, he makes an awesome boss killer.
If they could just toss a pit stop heal during levels and upped the XP rates or something it'd be a pretty great game to play once in a while, but as it stands now it's just annoying and boring. I sunk like 3 hours into it in my down time at work and at least 2 of them were spent being incredibly bored.
