(sorry for my cheap English)
I found this game when I looked up "Brainfuck game". I show respect for your kind level design and UI, include visualized memory. [step] feature was very useful for beginner like me. Colorful UI is also great, make me want to play (Only black and white ones(like A=B by artless) are look stylish, but made me feel hard to start out). If possible, I would like to see more subsection problems (and sections) added! The experience of solving problems step by step will motivate players!
I'm looking forward to release on steam!
