Well, controls being awful and needing messing around with in the settings is great first impressions isn't it. Suspect I'll bounce off this one quite quickly.
Don't think any of their mobile games stuck for me. Dr Mario was the closest, but it felt at times such a crapshoot of chance of what you get, and not very generous on ways to play on, so you do a few goes on one stuck level, run out of lives, go ahh fuck this, close the app and gradually forget to go back.
Them being tricky to play offline (hello Tube) never helps.
