Official update history
On the site: Build 1609067
Up to date
After having introduced achievements recently, the game now features trading cards. Furthermore the game keeps track of the efficiency of your designs by telling you your design's overall NAND-Count and by showing you how you compare to the rest of the world via leaderboards integration. If you messed up, you can now revisit your solutions and optimize them.
Changes:
- Trading Cards integration
- For every part you build the game will tell you it's total NAND count (including all the NANDs used by it's parts). Changing the design of a simple gate (like an MUX element) will influence all elements using that element as a part (e.g. RAM, ALU, CPU, etc.)
- After finishing a design, it will have a "Finished Design" and "Working Design" section, once it is in the "Completed" folder. The "Finished Design" shows you your solution for your best and most recent design implementation. The "Working Design" tab gives you the possibility to have another shot at doing the design and eventually improving it (may it be syntactically or nand-count wise)
- Steam Leaderboard integration: You can see how well your design is compared to your friends design and the worlds best design
- Loading an old savestate, should immediately give you stats for all your designs without the need of redoing them
- A lot of other minor bugs have been fixed as well

Thank you all for reporting all the typos and bugs you found! By now most of them should be fixed and a new update for the game is out, introducing achievements:
- Achievements added
- Fixed auto-complete bug under Mac OS
- Corrected many typos and did some slight changes to the specifications and manual (no impact on the actual designs though)
- Improved error messages for the verification process
Please be aware that some of the changes (incl. achievements) won't be accessable with old savestates for now.
