A bit buggy

Recently, I’ve downloaded this so I can re-experience my childhood game, and I love that it is almost the same! However, there are a few bugs that I’ve experienced time and time again. Sometimes, I’ll finish a level and it will freeze, so I will need to close it and open it again then redo the level with one less life. In the daily bonuses section, it will get stuck on the loading screen and not progress further than that. The last one is the Trial 1 arena, I click play and it just crashes. Any help is appreciated, I am playing on an iPhone SE if it helps

Pretty good!!

Well I like the game it’s different than most match3 games out and has lots of potential to become great but bugs are messing up my experience for 1, I’m playing on a a iPad mini 4 and some times I would beat the level and it stays stuck like its waiting for the cutscene but it never shows up and I have to beat the level again, number 2 problem that I notice is I’m not leveling up my team I would beat a level it tally’s up my points and I go to see the progress of my monster and it’s the same like it’s not registered my points to gain a level , I have beating many levels and still haven’t leveled up, I don’t want to keep playing and stay the same and lose all those points I should of gained!!”

Hi Mega,

thank you for playing RainbowTail. For #1, we do realize the crashing and stuck bugs. We are working to fix the bug and deliver an update as soon as we can.

For #2, Currently, the levelling up should be done by feeding the gemling with the same gemling (or the original form prior evolution). That would be the fastest way to level up a gemling. This is due to very high requirement to match gems in order to level up a gemling.

Thank you

A few things don’t work.

When I do the rockobo arena, it kicks me out of the game, and when I tap the daily rewards thing, it takes forever to load! Can you please fix these things? I will rate the game 5 stars instead of 4!
