Show HN: Terminalcore – The Rhythm Game for PC

Hey all! Built a PC based rhythm game designed around a terminal and ascii aesthetic. All built with Claude Code. Unsurprisingly LLMs are terrible at 'hearing' music so I had to make the beat maps manually. I built a separate tool to create the maps using a timeline editor to make it easier.

Started with 3 tracks one difficulty each, wanted to share before I went any further. Let me know what you think!
