This is a collection that covers all the ideas that have been thought of in Cracking Ice. The reason for this is because originally Craibing planned to exploit all the ideas, but found that the day when so many ideas would be completed was far away, so he planned to do a brain integration. Some of them have already been opened, and some are waiting to be opened (there is a certain chance that it is just a guess), which can be regarded as a convenience. You don't need to choose the pits you want to jump one by one, they are all together, just pick them!
Ps: Don't worry about ice cracking being a pitfall (it happened a few times in the post bar, but it was always a pitfall in Green Tintin), it will be updated slowly, but it won't be a pitfall.
