Very fun, lots of potential. There's a few bugs, like, if I level up right after killing the last enemy, the game just skips the level up reel or I get an overlay glitch where I can't click on the 'stop' button and can only progress to the bounty reel. And, sometimes, I can't retry after dying, only after I refresh the page.
There's some balancing to be made in regards to the bounty, the 0's are just too punitive early-to-middle game. And my build just gets extremely broken when I get lucky and am able to get lots of coins.
The fact that I can open chests more than once makes getting artifacts very easy, if we could only open it one time, or if the chest enemy was stronger, this wouldn't be an issue.
The focus power-up just seems useless right now, in fact, I can very easily beat the game without using any items, just weapons and artifacts.
We should be able to see the probability of getting skulls before clicking on the 'rest' button.
There should really be a way to alter the settings while in game, a pause menu, if you will.
The game is very damage-heavy, defense builds/artifacts are too weak.
