I couldn't even play the main game, as it crashed as soon as it loaded. At first I thought the shooting was broken, but then I figured it out...it's very hard to control, maybe a more in-depth tutorial? I don't know what space does, and the enemies don't shoot at me, and sometimes they just disappear. I don't know if the game is broken or if I just don't understand how it works...either way it's lacking polish.
Sorry to be super negative but the bugs hinder the performance significantly.
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.
