The web build was broken on my end, but from the concepts it seems super well done. I couldn't transition in between stages and start the boss rush itself. The animation is amazing though!
Yeah sorrya bout that I notice that people have been with the same issue, the current browsers are not "good enough" to handle my game, eaven in the windows build the boss takes like 2 seconds to load, if you like the game and want to play it better I suggest using the windows or linux build.
