I played the beta and its really good! It almost feels like the full game itself! The controls are simple and the level design was quite manageable. I am not sure on what the difference between weapons are. I also like the approach that defeating the enemies is optional. The surprise in the secret place was indeed a hilarious and welcome one. Also the damage buff bar was really useful and helps clear bigger enemies faster. I really enjoyed this game and can't wait for the full release or a new game!
