Fix it BEFORE you add more glitches

I paid for the expansion for this game and then the game went and deleted a bunch of data so now I don't have any characters from it so it won't allow me to play it at all and I also lost the cards I won from the battles I did play which btw also got reset to level one which again I can't even play because my new characters just disappeared. Also it still crashes and freezes and I'll lose even more stuff and when it's in the arena the trophy count goes back to zero after I had huge win streak. When it does freeze up it's the whole thing except conveniently for the surrender button, well that's great cause you know it's either I unwillingly choose to lose or I still lose. And sometimes the data will show characters or cards that aren't there and everything goes to zero whatever it is. Another thing is that when I try to restore purchases to try and get my stuff back it doesn't work like the button itself is broken. The game was one of my favorites at one point but now it's just a waste of space, time, and money at this point, I keep spending it and then it's gone.

Fix me!!!!

This game is awesome but there are lots of things that need to be fixed, changed, and added to this game.
1) I used to have this game and I got very far but then I deleted it when. I got it again thinking I would still have everything but no, I had to restart! It sucked. Lesson: Make a saving feature for people who delete the app.
2) The reason I got the game again was so I could play with my brother. But there is not a feature for playing with specific people. Lesson: Make it so you can play with other people of your choice.
3) I was playing in the tournament mode to win trophies. I kept winning the battles and getting more and more trophies. I went and checked on how many trophies I had total and it had barely moved! So I played one more game, won, and the checked on the trophies. It didn't change! I finally found out that you need to win 2 to 3 games before 1 game kicks in. This is super annoying. Lesson: Fix the trophy system please.
4) When you are doing a tournament battle the wheel thing with the sword that shows if you have a critical hit, a normal hit, or a miss moves way to fast. It spins so fast that you can't make a difference. In the campaign version of the wheel it spins at a good speed, but for the tournament multiplayer it spins way to fast. Lesson: Change the speed of the battle wheels.

Other than those things this game is super fun. Try it out and I hope you like it. 👍👍👍

Good, but with some glaring problems.

I LOVE this game. However, there are 2 problems. 1, it crashes after every battle and sometimes in the middle of battle. 2, and I'm not really complaining here, but every so often in the middle of battle, one of my creatures will SKYROCKET in health in power. Like, my well dressed wolf going from 10 power and 18 defense to 120 power and 216 defense. It's not very fair and it happens once or twice in every battle. But aside from that, GREAT game. Ps, it's NOT pay to win. I haven't spent a dime past the initial 4 dollars and I'm at level 90 with gold cards. Just collect gems from getting stars, wait out the hearts if u really need to, and try to win the black card tournaments. (I've never won one, but I usually end up in 10th place and get a gold card). Either way, keep up the good work CN!...and PLEASE abandon teen titans go...
