Yeah in future I would like to have more icons, and less text, so the standard cog for options is definitely going to be a thing.
Yeah coins give you gold and tiny bit of extra time. Some of them are really high above the ground because you can pick them up by throwing crates at them (depending on your Seals, you can actually get more gold that way). They are definitely on a big side, but that's s it's easier to collect them. Then again Mario's coins are nearly the size of Mario.
I don't know where else I should mention it's a lewd game. This is my second Demo Day, so I'm still pretty new to this. I still have no lewd content and all NPCs are just placeholders for future models, but I want to be upfront with people about it being an adult game.
I just uploaded new version of the game with improvements from the feedback I got this past week. I am going to do what you suggested with moving the options menu in next version.
Thanks for all the feedback
