Thank you for playing our game. Your idea is very nice, It will be more interesting with a limited time rule. Actually, if you upgrade the vehicle enough, you can pick up protester instantly since their convince point is less than your vehicle's convince point per second. This game was made in two days for a game jam so it not fully functions. In our completed GDD, there are various protesters types with various behavior like chasing, throw stuff, gun shot, scream, some special abilities... Have a nice time, thank you again!
