Movement was terrible - everything was too slow, the player would sometimes sink into the ground, and jumping sometimes didn't work?
The mouth sound effects were really weird, makes me question if this was meant to be serious at all and whether or not should bother leaving feedback.
There are places online you kind find free audio and other assets. Maybe look there next time instead of trying to record them yourself.
The graphics were also really bad - the player sprite for example was so blurry it didn't fit in with the other sprites, and was hard to tell what it was supposed to be.
