Amazing fan game overall, especially with the Crash Creator! People have already been making tons of cool levels with it.
That being said, I do want to report one Crash Creator bug I've noticed in v0.92c. If you activate a nitro switch crate, it will blow up every nitro even if some of the nitros are set as outline crates and need to be activated first. If you then activate the nitro with a normal switch crate after hitting the nitro switch crate, the nitros that were outline crates then become persistent.
Also, there is one single change that I'd like to request which would make things like creating calculators in Crash Creator possible. Allow the explosions of nitros and TNTs to activate switch crates like they do in the mainline series. This would just allow so much cool stuff to be made and allow people to also make more elaborate switch crate puzzles.
