Now that we have refined the collision detection for the monkey and the tiles, it's time to add some enemies for our monkey to avoid, and we also need to find some interesting items for the monkey to collect. Adding these objects into our game will introduce the first level of challenge for our players.

We've already learned how to import actors from StencylForge, and that's where we'll find the new actors we're going to place into the jungle scene.

Downloading the enemies and collectibles

The game file to import and load for this session is 5961_03_05.stencyl.
