Show HN: Chess Puzzles, but for Developers

Dear hacker friends! I will keep sharing my updates here. I just finished and released the Engine 1.0 of the app! It’s amazing! Please try it out, I am still waiting for your brutal feedback.

What a weird place is this hackernews? why no one cares to write a single comment here to share their feedback with developers

Just in case you want to contact me directly, there is a contact form on the web app. I am sure, you'll find it.
