I'm about to start making a computer in your simulator, and I was making one in Roblox!

I also made a counter from the Register stuff you made but I used a Data Flip Flop instead of a Data Latch (data latch example at 11:11 on video How Do Computers Remember? - YouTube

I had an enable count and a clock and when enable count is on, it will be able to count every clock pulse.
