I've been working on building a game called "Pumpkins" in UE4 for quite a bit now. The art is still in a fairly early state but I'd like to talk about the basic idea and gameplay systems. The idea is pretty simple. Your goal is to collect all the pumpkins in a specific area and drop them off in the designated drop off zone.
There are some creatures that will patrol each area. The player's goal is to avoid them while collecting the pumpkins.
Any contact with the enemies will cause the player to drop all their pumpkins and flee from the area. They will have to try the course again.
The game is simple in its design but I've had an awesome time putting together all the systems that make it work. Everything was done with blueprint. I plan on continuing work on this project as well as documenting some of the cooler systems on this blog.
