1 ... 1st nostalgia water world I have seen on this Game Jam ... interesting
2 ... maybe add zoom option (some people might complain they are blind)
3 ... maybe adjust camera character follow up: game character is visible little closer to the center side -> now sometimes character almost falls out of camera (top side)
4 ... looks good for 27inch display full HD
5 ... <forced camera moving down> all the time <after some time of playing> feels forced:
5.1 . do you want to achieve feeling of sinking (then that probably be perfect idea)?
6 ... this bg circle shader on BG around you gives extra dynamic -> very good
Design
1 ... movable GUI on screen or more centralized to gain eye focus
2 ... add mouse hover/ click actions on GUI (currently only is keyboard interaction)
3 ... show my amount of gold (currently I am not sure where my money is)
4 ... the touch of auto pushing you down from base in 3sec is good micro improvement (normal players would hardly see)
5 ... is there faster pull for this harpoon?
6 ... create not forced tutorial
6.1 . center bot side, text effect sth. like (little more tuned): "Right click to fish"
6.2 . adding target element
6.3 . auto turn off after game detect player is good
7 ... let me turn off all GUI (GUI animation scale down to the button) -> so I am able to see entire world,
7.1 . GUI might feels forced sometimes
8 ... try zoom-in/zoom-out channeling of harpoon -> to give feeling of control (currently bow has low impact or might be hardly visible - small)
Controls
1 ... takes some time to get feeling of controls (check Design 6.)
Sound
1 ... chilling sound with some noise -> good work
2 ... "welcome friend" I love this store voice acting
3 ... sounds does NOT feel repetitive -> very good
