Nandgame. Уровни Software. Keyboard Input

Я прохожу игру nandgame ( https://nandgame.com ). И не могу пройти уровень Keyboard Input из раздела Software
Я написал код

 # *A (0) -> next output   
A = 0x1000   
D = A   
A = 0   
*A = D   
 
# Store pressed key to D   
A = 0x6000   
D = *A   

# check with prev clock pressed value   
A = 2   
*A - D; JEQ   
*A = D; JEQ   
 
# get store address   
A = 0   
A = *A   
 
# store pressed key    
*A = D   
 
D = A + 1   
A = 2   
JMP  

Но я не успеваю буквально на 2 такта, для прохождения уровня мне надо сохранить значение до 10 такта включительно, но я сохраняю на 12 (на первой итерации) и на 10-ой на остальных. Помогите исправить код (сжать или вообще поменять идею)
Note: на сайте используется не стандартный assembler, а свой со своими правилами:
**Assembler quick reference**

Syntax is: destination = calculation ; jump-condition Destination and jump-condition are optional.

D and A are the two registers. *A indicate the value in RAM at the address contained in A.

**Examples:**
D = D + 1 Calculate D + 1 and store the result in D.
D - 1 ; JGE Calculate D - 1. Jump if the result is greater than 0. (Result is not stored.)
A = 1234 Store the number 1234 in the A register.
# Hello Comment - ignored by assembler
**Calculations**
D + A
D - A or A - D
D & A (Bitwise and)
D | A (Bitwise or)
A+1 or D+1
A-1 or D-1
-A or -D
~A or ~D (Bitwise inversion)
1 or 0 or -1
In all cases can *A be used instead of A.

**Destinations**
Any combination of D, A and *A can be used as destination. Multiple destinations are comma separated, e.g. D, A = 1.

**Jump conditions**
Jump when result of calculation is:
JEQ equal to 0
JNE not equal to 0
JGT greater than 0
JGE greater than or equal to 0
JLT less than 0
JLE less than or equal to 0
JMP Unconditional jump (regardless of the calculation result.)

**Number instructions**
A can be directly assigned a number. Example: A = 47.
Numbers in hexadecimal is prefixed with 0x, e.g: A = 0x7FFF
Numbers in binary is prefixed with 0b, e.g: A = 0b010111. Underscores can be used to separate digit groups, e.g: A = 0b_0101_1100.

**Comments**
Lines staring with # are ignored by the assembler. They can be used for comments and documentation.

**Labels**
The keyword LABEL followed by a name makes the name represent the address of the following instruction. This address can be assigned to A before a jump, e.g. A = LOOP.

**Defines**
The keyword DEFINE followed by a name and a number will cause the name to be replaced with the number when it occurs in other instructions. For example the two lines:
DEFINE foo 0x7FFF
A = foo
Is equivalent to: A = 0x7FFF

**Multiple targets**
It it possible to assign a result to multiple registers.

E.g. D, A = D - *A The result of the calculation will be written to both A and D.

Any combination of A, D and *A can be specified as destination.
