Reaction thumbs was my first ever published project. Players were tasked with tapping lights as they appeared on screen before they turned off and seeing how long they could maintain it.
Although the game had a simple and weirdly addicting charm, the goal wasn't to make the best game but to learn how to finish a project and deal with all the admin surrounding launching a product.
I still remember my nerves as I submitted the game to the store and the rush of excitement when I saw over 100 people had downloaded my little demo game. No matter what the reviews, plays or views on anything subsequent, nothing will mean as much as those 100 people did to me back then.
