Have put a few hours into the game and it has been an enjoyable experiance. Have made it to the fourth level a few times but can't quiet push through to number 5. You unlock more guns as you play the game which changes what you get in the chests it adds variety, found over time you learn the mobs and it gets easier to progress from level to level and lucking out on an over powered gun or 2 can help along the way as well. Each level has a theme and certain monsters are different. Would recomend to anyone who likes fast rogue likes, first 3 levels is about 20 - 30 mins and the game has a save function at the end of each level at the lift, so you can walk away and come back later.
