Merge Packing

Merge Packing Project Description

This game is a mobile merging game where you drop toys in a box to clean them up. Merging two of the same toys makes one toy that is one size bigger.
Every merge gives you points depending on how big you merge. Every 200 points, the packing alien drops packing peanuts in your box to fill it up quicker.
When your box is full the game is over. To clean out packing peanuts, you have to merge 2 of the biggest toys, this clears the packing peanuts and removes both of these big toys.

What I made

For this project, I made the GameManager, which is the biggest thing I made since it does everything with the random items you get, the game loop, and it handles the score/high score.

I made all the UI elements and the menu's. And I helped with the items and the merging, but this was mostly done by our other developer.
All my teammates are linked on the itch page.
