I love the game, but I wish you could replay old levels after winning...I never finished upgrading my cars, and I want to explore more without replaying the entire game.
This is an amazing piece of work, and I would love to see it completed...but the technical issues arising from flash are far from insignificant. Have you considered making it as a downloadable game using RPG Maker or even in Unity or some such? You've done a great job here, but I'm sure you could do even better if you were using a less limiting medium.
Great game, it was really a proper sequel to Rebuild 1. It would have been nice to be able t edit character appearances manually.
@Everyone who's commenting on the difficulty.
Are you playing this on easy or something? Impossible is far harder than Rebuild I (at least for me).
