I see some of the issues yeah, the green weapon one was to let players explore and wonder, that's why it shoots stars but I think I could have improved the way I encourage that exploration.
For stats, I didn't make them very clear, I just showed some basic graphics and let player guess and connect dots to see how they would navigate through the game yeah
Field being small IS A BIG ISSUE yes, I don't think 600x600 was the best decision I made.
Thank you for such detailed review <3
