OMG! O M G ! What a stunning game!
I managed to get to the last challenge. The only thing I didn't know how to do was fix my car XD. When I tried switching cars mid race to get around being damaged it still had the damage remembered on the other cars which was nice.
Fantastic menus and credit screen also. I also loved all the hud stats and map of the race which was subtle but helpful.
I enjoyed most the replay camera. It worked perfect. It was a blast seeing everything sped up or slowed down from different angles and in different levels.
When I would replay the camera for example sped up then the next level I played would be in also sped up mode. This might be a bug ? or a feature cause sped up driving was really fun.
I am gonna give it another go after the jam when the updates come and I cannot wait!

Wow thanks Mel for the lovely review and for obviously really diving into the game I really really do appreciate it and cool screenies. There are a number of issues which we are addressing now but you have found a new one so on the list it goes :) We hope to have an improved version to upload after voting has closed.
We have never done Jam before and it has been a lot of fun, very useful and very rewarding. I think Chris will need a little time to recover, always harder on the programmer, but pretty sure by next year I can persuade him to do it again and I think we will try something completely different.
Anyway thanks again and hopefully today we can make some time to check out all the other games.
Mels, it's so nice to read your comment, it means an awful lot coming from someone with your talents. I mean just look at what you did on Jern's SHART game :)
There is so much wrong in the demo due to the deadline and having to get something out that I can't watch it being played at the moment, so busy working on an update to make it something I am happy with so do check back later.
Thanks for the screenies as well, I think the replay mode is my fav bit at the moment, its much better with more interesting levels, the fun bit of the game is getting the big jumps right.
