In most games/cartoons the interactable stuff is clearly different from the background, you did that well for the crowbar, shovel, tnt and keys, but for some interactive stuff like in front of the kraken, the door, the buttons, it wasn't clear from afar what you could interact with, so I lost a lot of time moving everywhere.
While this is fine in a short game like this, I think in a large game that'd lead to some frustration, and while I think you want the player to feel some frustration, it should be about their skill/the fact they haven't explored enough, not because they could miss the "press e to interact" overlay because they were moving too quickly.
(but maybe I'm overthinking it ^^')
I really didn't have testers and I did not think about this because I know the map , but actually I thought that I should make things harder so the time limit puts pressure and makes the game fun. This is my first time making a game and with no experience so thank you so much for playing and explaining to me what is better for it
