Just an opinion on the attack block that I hope is taken into consideration:
1. The attack block shoots too slow, given that the price is 5x greater than the other furniture in the shop, there should be a manual option of adjusting the rate of how fast it shoots
2. Initially I thought it would be able to move around like a robot spider attacking people, so that would be cool
3. Making it be able to shoot through certain objects
4. Making it able to attack everyone including the owner (set "Protect" to "Nobody")
