This game is really fun. I enjoyed it as soon as I heard the banger music which plays immediately, and never gets repetitive. The gameplay loop was really fun, and the mechanic of needing to carry the armoured elves away from the presents and killing them made the game better on a whole new level.
One issue I had was some lack of sound effects. For example I couldn't really tell if an elf had died, and a sound effect could have definitely helped. The art and animations all feel really smooth and match the overall style you were going for.
The game is also really hard, and each round gets more challenging. I got to round 11 and was overwhelmed by three armoured elves targeting my present, and without the ornament bomb, I knew I had lost. Great game overall!
