It looks awesome. Can't wait for a moving screenie/video.

I wish you the best of luck with this and hope you finish. I myself started once on the same project for the 89 but I didn't continue.

Impressive graphics so far. I really like the crafting/furnace/inventory interface looks almost like the original one!
Thanks for giving the rest of us inspiration.

The size seems quite small. I guess you could eventually add much larger worlds and features. By the way, how well does it handle incredibly large stashes of falling sand?

For the old Nspires, maybe there could be an option in the menu letting people switching between two different tile set, where one of them would have a much brighter contrast, allowing the game to be easier to play on grayscale models.

That could be a 3rd option, but I doubt many people will be willing to play an ASCII-art-based game on a 150-240 MHz calculator

Thank you all for your encouragement, that really supports me and makes me confident to complete this huge project!
I'm making great progress with the saving system and I'm sure, I can upload the current version soon.
I like the idea of a non CX version, but I don't think both have to be in 1 file to change them while playing... maybe 2 files with diffenrent tile set?
@DJ Omnimaga: Sure, I think I'll do it like in the Alpha versions of Minecraft: you can choose different world sizes. How many Blocks do you think a Nspire could keep in the RAM if every block is saved as a Integer between 0 and 300 in a 2 dimensional table? Don't worry about the performance, by now, only the visible blocks get updated (except furnaces).

The problem with ticalc is the waiting between the time you upload your file and the time it is being approved. Of course, you still should upload it to ticalc.org, but you can also attach a file to one of your posts (preferably the first post of this topic so the file can be found easily) so we can access it without waiting for it to be approved.

Also, there is an "edit" button to edit posts so people don't double post all the time. Double posting is allowed if your new post is 6 hours or so (or maybe one full day) after your previous post, or if you make an update. I guess this time it is okay since you made an update, but I was just telling you in case you didn't know.
