Thank you!!! Your sincere advice made me think about some details; the points you mentioned above are also areas where I hesitated when designing the game.
- I also don't know why the trash is on top, making it hard to pick up, very strange;
- 'Arch' means the printed new ocean 4D architecture; Hmm, if I develop this game long-term, I will write it in full because this is just a demo, haha; mainly because the word 'Architecture' is too long, it doesn't look good on my UI panel, so I abbreviated it;
- Regarding the game loop, the original idea was to simply convert as much garbage as possible into energy and materials to print things. In fact, the amount of trash decreases in the game if you play further, but the rewards in the game are not very prominent. I hope the game pros can provide suggestions.
- Regarding hotkeys, I originally wanted to use the spacebar, but for the sake of a clean and beautiful interface, I used letters like X and N instead. Next time, I will improve the interaction method!
