Alright the two real bugs are the WebGL build and the bullets frequently hitting invisible walls and killing enemies without any visual feedback. Every thing else has purpose.
There is not a lot of indication on stuff because of the achievements(actually, another issue, I should of written the word achievements) on the right on the screen. They are there to push the player to figure out the mechanics, as it is more a roguelike/learning by failing game.
Also... Progress bar is failing. I have to blame the 4K textures.
