It's very cool that you were able to make a 3D game for jam. Enemies are pleasantly grab and just as pleasantly throw at the nearest object that catches the eye. The only thing that spoiled the survivability was the spawn of enemies of the next wave right behind my back, which are not marked in any way by sound or possibly visually. It's not bad, but I think if enemies have a sound effect when they spawn, the game will feel even more enjoyable
