Thank you for the honest Feedback.
You dont need to worry, i dont take it the wrong way as long as it isnt a personal insult so most feedbacks are save and i am glad for every honest feedback i get. I plan to develop the game further, the next step would be a Demo Build so there is a long way before that, and you can point out as much as you like i am gathering the feedback to improve the experience in the game and my skills too.
the fish shadows where indeed drawing in my attention, i did have them on the todo list, but with the time for the jam and the last bugfixes they still got out of my focus.
The Backpack was my mistake, i intentionally wantet to use the x patch on the button, then i was wondering if this was clear enough so i decided on a bigger button on the right sight. So yes you are right that might be confusing and it helps a lot that you say that the patch is drawing the attention, that was a really hard ting to decide wether it is enough or not.
The Start Shift button also, for the time being i will make it bigger and more readable, but i already are gathering ideas hiw it could fit better into the screen and enviroment.
I am glad hat the music and art are working good for you together and that you could enjoy it, i specially made the art for the game and the music was a long and very carefully search so thanks for mentioning that :)
