What about adding a mechanism in towers where you need to shoots bows to open up corridors/fences to let you advance to the next room.
For example, there is a medieval like castle blockade. And the only way to get past it is to shoot arrows at a certain switch.
This could be implemented in a lot of Towers and could make use of arrows and making the players use these more.
Im leaning towards those targets in the archery mini game being placed in locations a player can’t reach, and the only way to hit the target is to make use of your bow. Hitting it a certain amount of times opens the door and can let the player advance to the flag room.
Arrows could even be used on making setting traps in a tower for example if you hit a switch with your arrow. A spike will appear in a set location and will hit another player.
I’m not just talking about towers but this could be added to those baddy caves. To make it more entertaining and look the place is more “filled?”.
I’m not good at explaining things but you get the idea...
