The Beta currently only contains only one level, one boss and one type of enemy, but soon this game could have double, if not triple, the amount! Above is the official logo for the game. The final version's logo is basically the same, but without the "BETA" text... but the final version I suspect won't be released until sometime in 2018. If you want to download the game, the link is below!
I'm going to be selling the final game, but the Beta will always be available for free.
