I saw this before. This is an over used minecraft tutorial/thingy. I don't know where you got it from. But what I do care about is that you couldn't change some things about it. Like the lava. You could have just duplicated the water re-skinned it and changed the script so it deals damage per second.
Epic game. I would love to see this concept be expanded upon. If this had extra features it could make a great paid indie game. If it had extra enemy types and maybe some sort of upgrade system. Maybe customization I would love to buy this. This also seems like a great app for smartphones/tablets. 5/5 for a truly amazing experience :D
Hey every one who plays this game. They did use somebody Else's work but if I can remember correctly you can buy the whole unity file and modify it and use it however you want so technically they got permission from the people who made the amazing visuals to use it.
Hey I just saw your game and I'm not going to criticise the game yet as I can see its a WIP. But I will give you some friendly tips. First thing's first add a mouse lock script. It makes the game a bit more enjoyable as you don't need to worry about clicking on something you wasn't meant to press. I would also make the bullets travel at a much faster speed as the bullets seem to just fly out of the gun and they fly out at a really slow speed and in popular fps's like Call of duty or battlefield you don't see that. I would also work a bit on the camera placement and I would freeze the camera in the main menu. Other than that it's a nice start. I hope you have fun making your game and if you need anything just message me.
