Wow we love this kind of feedback thank you very much for all of this, this exactly the kind of stuff that makes you keep developing the games, about your recomendations:
First: yeah that screen was added post jam, I didnt wanted to affect to much the original build it felt unfair to update the game, we added because a lot of the comments where about we didnt have any tutorial or something, the change between the 2 miningames is rushed you are right we need to add more visual feedback and a little to let the player notice that is another stage
Second: yeah we noticed the O symbols was a mistake we are going to rework the patter to make them fit more in general with the memory idea and make them different enough
Third: you are totally right about this we didnt added anything in the game to know what to do, we added some info to the game pange an a trailer of how to catch creatures, but you are totally right about this
Forth: yeah it was another minigame when you need to use press the highlighted arrows to get "closer" to the fish and collect it
Yeah we were on stresss in the last minute, it was a miracle that we were able to upload a playable build, thanks alot for all the feedback is very helpful and we will keep working o this game we really like the process of making it and we see potential in the idea!
