I downloaded this for free the other day on my Vita and was all set to like it, however it's set up with the now standard 3 star ranking per level, something like Angry Birds. The third star is always for beating the level in a certain amount of time.
The issue is that Chronovolt tries to have a narrative. That's great, but it interrupts gameplay with the same plot-filled text boxes every time you restart a level. When one primary aspect of your game (time trials) is suggesting you ignore another aspect of your game (plot), you may want to rethink that design document. It wouldn't be that bad if on the retry, they skipped the dialogue, or if playing through the story version of the level unlocked the time trial version. Honestly, anything. As it is, I try to launch my ball very quickly to get that time trial star and the game abruptly stops my ball for dialogue. When I click the dialogue, my ball goes flying off a ledge.
I don't want to hate on the game. I absolutely love the character design for Jessica Chase and the art for the game. After 2 levels, I gave up on the time trials, and after that, I felt like the game was penalizing me and telling me I was playing wrong when it would throw in my face I didn't "fully" beat the level with 3 stars. I feel they could have done better.
