Yes, the game is in very early stages so pretty much all assets are placeholders.
You can get more than one weapon already but what you get to chose on level up is random so you might have been unlucky. I don't want them to be perfectly balanced. Since it's random which one you see except the first one you will not be able to pick the best ones consistently. So it's fine if some are better than others - within reason of course. That being said, current balance is not what I plan but since there aren't many harder enemies there isn't much to balance them against at the moment.
Right now all weapons can be chosen as a starting one but that will change, since some of them just don't make sense as starting one. Like the rotating discs which really only work as support weapon.
Thanks for playing :)
