thanks for your feedback!
On multiple lives: I think it's best to leave it at "permadeath", as it is a high-score based game and not that difficult anyway, when you get the hang of it. Multiple lives would make it even easier and push play time considerably over my targeted 3min goal.
Starting countdown is good, I'll put that on the list.
Load times: Yeah, they are quite a bit longer on Android, there quite a bit of pre-pooling of gameobjects, maybe I can bring the number down a bit. What device are you using?
Controls: Virtual D-Pad is on the roadmap, I got the same feedback from a friend of mine.
