This game is probably one of the best free web games currently on the market, and one of the better ones released this year, and it's still almost a full year until it's steam release. However, the huge RNG aspect makes it so runs either go to floor 5 and get stomped 20 times in a row, or make it to floor 30+ easily.
I'm not suggesting a change to it cause it's what makes the game fun and challenging, but I do want a way to see builds at their full potential.
Either a sandbox mode or some way to dictate what weapon(s) you want to find more often through some kind of random event on f1-3 would honestly make this game be really interesting, allowing builds that have never been seen before, and allowing floor maximums that have never been seen before.
The sandbox mode can obviously disregard any kind of leaderboard you may set up, and the random event idea would be like "Which offensive path do you find yourself going down, young one?" then the player picks one (melee, archery, magic), and then those weapons or items relating to them (ie shield for melee and arrows for archery) would show up 20% more often or however much.
