Hi fellow UE5 developer! Very cool idea! I feel like the concept of a caveman just destroying aliens with a club is the strongest aspect of the game, it definetly makes you look forward to playing it! As far as the gameplay goes, i liked the movement and attacking but i felt like the cooldown between club swings was a little too long for the kind of power the club offered; i felt like in basically every situation the gun was simply better and safer, especially because the enemies could only walk towards you without being too fast. Keep it up! Maybe next time you could try to have an even more complex map or enemies!
