This is why nobody likes VHDL. This is another one of those logic games that have troubles emulating building a latch from scratch. I had the same problem in Shenzhen. You might as well just get into programming real VHDL instead of playing games. The game skips making a basic D Flip Flop and gives you a pre-made DFF circuit that doesn't have an enable pin, because the game engine doesn't support it. If you try, it'll give you an error about illegal cycles.

Disappointingly bare experience in the "from NAND to CPU" genre. You do get to build a CPU, but you don't get the satisfaction of actually seeing it do anything, programming it in any way. The prize for tediously rewriting the connections written out for you in the problem description into the syntax of a hardware description language is only a popup window with undecipherable testcases.

Definitivamente recomendo se você já teve contato com conceitos de eletrônica digital, caso não tenha tido, você provavelmente vai aprender jogando, mas com certeza vai ser muito desafiador e até frustrante.
