Weird story, but I started making games in PowerPoint. One day, I just thought to myself "Hey, if I can make buttons that can go from one slide to another, then I can probably make a game." So, I started experimenting, and for about a year and a half, I was just making games in PowerPoint using that method, and it was pretty fun. Then I learned PowerPoint animations, and that took my game creation to a whole new level of PowerPoint. Of course, I was only spending maybe a couple of hours every month on this, so nothing much. Some examples of games I was making: A card game where you'd flip two matching cards together, a duck hunting game where ducks would fly and you'd try to hit them and reload your gun, a basketball game where you'd have to click on the hoop in the correct positions while your power bar was at the right amount, a clicker game with upgrades...)
I continued making games in PP for about a year, and then I stumbled upon Brackeys for the first time. I watched a couple of his videos, but couldn't really get myself to start anew, so I continued making games in PP. A year went buy, and I started to feel very restricted, so I went back to this wonderful Danish man, Brackeys, and finally got myself to download and start using Unity. I've been making games in Unity for almost two years now, and I absolutely love it.
