Im still on the fence about controlling it with the mouse, the feedback is loud and clear and they are hated, in their current form they are too hard to use and the difficulty wall at the start of the game is immense. But in my opinion with some modifications and a proper learning curve (plan on doing levels) the controls could be fun and challenging. My issue with WASD controls is that it boils too much of its difficulty and in order to balance you have to throw more enemies at the player, i will test a lot with mouse __and__ with WASD and see if people think mouse is more bearable, but that will come after loads of testing. (Also WASD is done to death in top down shooters, i want to come up with alternatives)
the sides and corners were intentional, quickly into playtesting i realized that hiding in a corner made the game exploitable, you could sit in a corner, kill, grab gun and go back to hiding, i tried to push the player into the middle of the arena although i failed telegraphing that.
Im glad you liked it, i really drop the ball on testing it and the difficulty is 11^2, but that will change.
