20 Minutes Till Dawn is a thrilling roguelike shoot'em up that puts players in the middle of a horrible survival journey.
At the start of each run, you pick a character and give her a weapon. Then you have to stay alive for 20 minutes while monsters keep attacking and you add to your weapons and skills on the fly.
On defense, stacking Dodge and Move Speed is the best thing you can do for most characters. You have a chance to avoid all damage from a single hit if you use Dodge. Move Speed makes your character run faster.
After every run through 20 Minutes Till Dawn, you get something called Souls, whether you win or lose. You should mix and match the different passive perks that runes give you based on your character.
Have fun and good luck!
