I am glad for your achievements.
1. Oh, this is extremely important. If the game does not adjust to the screen resolution, there is a high chance that it will not pass moderation on any web platform. (I am not even talking about the user experience.)
2. Yes, I understand that in the jam you did not have time for an interactive tutorial. It was enough for me that you had a guide "how to play" inside the game. So I will not punish you for this. I said this for the future. And no, you are wrong, all tutorials should be interactive. Otherwise, you can lose many players. The player wants to play, and not read long guides "how to play".
3. I do not understand how this problem arose at all. You definitely need to find a solution to it.
5. I did not like this. Your multi-tool works, I can plant a seed while holding a watering can in my hands. But, still, this is a questionable solution. Also, I can't open the panel with seeds while holding a watering can. Also, I can't remove the watering can with the right mouse button. Anyway, those hateful panels again.
7. And you did the right thing!
9. Yes, you've played more than me, you know better which solution is better. But still, think about making the player move the mouse as little as possible and click as little as possible. I really think that this will improve the user experience.
