The voice acting was really really good and this is also one of the few games I've played which have felt like they have a complete story behind it. Well done there! The music and audio also fit very well too!
Maybe someone else has pointed this out already, but you should definitely start the timer from when Charlie gets unleashed rather than (I assume) at the very start of the game. I lived way longer the second time I played but my timer was at like 29 seconds whereas the first time it was over a minute.
I'd also love more info like a little arrow indicator on Ralph showing which way he'll go when you release or a power meter.
Overall super fun game though!
