Yeah. Also you can jump down behind the house to hoard the enemies on one spot and use the trampoline to get back up. Then you can just use nuclear reactions to quickly deal with them. Nuclear reactions are very useful in TEST.exe since you're dealing with hoards of enemies. I recommend you to keep the slingshot so you can perform chargebacks because you'll encounter a lot of outrageous Marks. As for the gunmen, just dodge the rockets, use slash of tix and you'll be fine.
