Thanks for the feedback rustybailey! I too agree the zombies are difficult. The trick to them is to jump over them and attack. I have found after releasing the game that LMB would be a better fit for attack as when things get intense it is difficult to manage jumping, moving, and attacking all with a single hand. I have updated the game to allow the use of both SHIFT and LMB but waiting for approval to upload it. Once the Jam is over I will be updating it regardless.
