Game is pretty direct at the theme and you can easily recognize it. It is good that you created a tutorial page to know what to do. in the tutorial last page you say goodluck surviving 10min. I tried it literally WHHAHA, but somehow even though I thought I made the perfect run I cant last 1-2min the drain is pretty fast, and a simple mistake is super hard like in real life, don't know if that is what you going for but. I think the game needs some form of balancing a bit more and some other things to do? other ways to get some supplies or so. add some quality of life and a bit more playtesting to other people to get insights. but for now it is solid and have a game loop. Art style is good and have a certain charm in it.
