Icecave sample level
Map16 for FG is on page 6, and the bg is on page 13. All the bg is is the smb3 underground, I don't know why you'd need a sample but here it is.
Here is the final tileset that I am going to add for C3.
I truly appreciate all of the nice things that you've said about me. It has been a great honour to provide these sets to you, and know that you appreciate them. Things like this is what really keeps me going in this community. I have been around various game making sites for years, those of you who've read my piece in the wiki know this, but I have found that the SMWC community is the greatest that I have ever associated with. I hope that all these sets, and others I have released, will aid you in all your hacking and game creation endeavors.
I hope that everyone has had a wonderful C3. This is the first time that I have participated in this wonderful event, and I have just loved it. I do so look forward to the next C3, and I will try to have even more for the community the next go around. Thank you for visiting my booth. Goodnight all, and good luck.
