First off you need to let people know what the controls are as in this game you use the arrow keys to move and the x key to interact outside of putting it into full screen I did not see you letting people know the keys to use on the keyboard. The reason why I know that is because I pushed every button on my keyboard to see what would happen, most people do not like doing that.
Also right now it is very short and not much to do outside of picking 3 flowers and talking to 2 females. While I see you have a bunch of stuff in the gifts that you can give them which you do not even need.
In fact you do not even have to talk to them just go to the heart and have sex with them until you run out of Stamina which you can not even refill also your thirst and hunger does not move.
While I am just pointing out things that can be improved on. You put survival in the name of the game which means you will need to get food ,water, just like a survival game that you would play.
Keep at it a good place would be creating a very basic crafting system in which you can make a few tools, like a stone axe you would need a stick, a small rock and a piece of vine which you can gather up from there you can cut down a tree get logs that will be able to build a shelter(house ect).
Also how did you end up on the island? Was the 2 females with you?
These are a few questions that you should let the players know as part of your story element.
i disable the script of Thirst & Hungr because im still not make a food and water or fruit yet (also Modeling) and still not make an Inventory system yet. i make the game just in 1 day, except the 3D modeling. i know it's a 2D game, because i render the model with 2D sprite (like Diablo 1 and 2).
about the control. yeah, i was forgot about that.
for the next update, i planned to added Message TextBox, Inventory, Save & Load, PopUp Text, and of course Food, Fruit and Water, and a vew Item.
for crafting system, yeahm i was planned it too because at this game, you will hunting to get food or resource too.
you'l also explore the dungeon and mining for resource. (it's good to build a house or other building)
and about the Story, it's my problem at the moment. i still don't know what story should i make for this game.
there will be another people at the island. ( more females, and a some males ). its about cruise ship drowned and make a some people ended at this island.
mybe you are confused about money at the give category? LOL yeah, me too i don't know why i put money for it.
for now, i'll just focuses on the GamePlay. about story, maybe i'll ask someone here to help.
and so that people not confuse about the control, i'll try to improve the UI.
Sorry for my Bad Englis. and thank you for your reply
