This game rocks! It's a ton of fun, you have great audio and visual feedback and great style! I agree with many here that this could make a really killer multiplayer game if ya'll want to branch into learning multiplayer!
Two pieces of feedback from me: The camera sensitivity on controller is very high and it made it pretty difficult to play. Turning it down a bit would be great, but a sensitivity option would be even better.
I absolutely love how this game sounds, Mya did an outstanding job with both the sounds and the music. If you want to push it over the top however, I would look into increasing the sound variety a bit. This game has only a few actions that repeat a bunch and it seems like there is one sound effect for each. For common actions that the player is going to be hearing a often you want to try and have two or three different sound effects so that a repeated sound doesn't overstay its welcome. However even if you only have one sound effect, you can randomize the pitch a tiny bit each time it plays and that does a lot of heavy lifting for a tiny bit of work. You don't need any special middleware to do it either, in Unreal sound cues you can add a modulator node in and it'll make your game feel even better.
Awesome job! I'd love to see more from ya'll!
