This is the first game prototype I built in Unity after doing some Unity Learning Pathway courses in Dec/Jan. It's my take on a simple tile matching/combining game, the idea of the game is to combine primary colors (Red, Yellow, Blue) into tertiary colors (Purple, Orange, Green) and then ultimately into Brown. Currently there are 3 prototype modes:

Brown Disappear
In which the Tiles disappear when they're made into Brown ones

Brown Align
In which the Brown Tiles need to be aligned into 3 or more to make them disappear

Brown Fall
In which the Brown Tiles fall to the bottom of the column when created, and then disappear when the whole row is Brown

This is the second game prototype I started building in Unity. It's an experiment of a variation on the classic Mine Sweeper gameplay, but approaching it from a mining concept, where the goal is to find a path from the top of the screen to the goal at the bottom. This is still very early, and I'm trying different things to see what is fun and what works.

This 3rd game prototype uses a classic pipe connecting game idea and allowed me to experiment with creating and using sprites. After making the game and iterating a little I quickly realized that in its current form it was very easy and that making it challenging and fun would require significant additional investment. Given I'd learned what I wanted to about Sprites and some other bits, I decided to leave the prototype at this point.
