@alexcooldev released a 3D chess game originally built in two hours and, after reader feedback, spent one more hour adding AI vs. AI mode, a cinematic battle camera, and an 18th–early 19th-century European army–inspired skin, plus bug fixes and performance improvements that make the game playable on mobile. The author credits iterative prompting and user feedback for the rapid enhancements.
@alexcooldev spent 2 hours vibe-coding a 3D chess game, then spent an additional hour improving it after user feedback (tweet posted 2026-08-04).
Got a ton of feedback on the 3D chess game I vibe-coded in 2 hours and I shared earlier, so I spent one more hour improving it.
New updates:
→ AI vs. AI mode
→ Cinematic camera for watching battles
→ A new chess skin inspired by 18th and early 19th-century European armies
→ Fixed bugs and improved performance (you can play on mobile too).
AI is still crazy. I just keep posting, reading feedback, and updating the game with prompts. 😃
