Learned of this game through a piece of paper in my mailbox which is not something you see everyday.
Anyway, very fun and unique game! It has the fun of playing with the half-life gravity gun but with even more fun trick shots possible.
I played it with mouse and keyboard since I have no controller and it works fine. One thing it could use is a sensitivity slider for the mouse, but I can definitely manage.
Keep it up, looking forward to more!
