Thank you for your feedback, and I'm glad you liked the ship builder and the idea. I'm sorry to hear about the frame rate issue in the HTML version – that's definitely not the experience I want players to have. I appreciate you pointing this out, and I'll investigate to ensure that all objects are properly destroyed. It's possible that there are too many enemies at some point for the web version to handle smoothly, and I'll work on optimizing that. Your input is valuable for improving the game. If you have any other details or suggestions, please let me know. I'm committed to making the game more enjoyable for everyone. Thanks for playing!
