This is one new thing I never thought I’d be able to do! It sounds so complicated and time-intensive, and although it was hard, it was way easier than I thought.
We have a Nintendo Switch, and we like playing the Labo game on it: you get a flatpack of cardboard patterns that you fold and turn into various creations, which are then incorporated into the game. For example, we have made a piano, a steering wheel, and a pair of Virtual Reality goggles.
Although the game does have VR games already, there is an option where you can design and play your own creations.

Although the game creation aspect is aimed with the novice (definitely me) in mind, as you can imagine, it still requires a lot of concentration and mental work to get an end result. My goal was to make a simple game: the player throws a ball through a hoop. After a little time, I managed this, happily checking my progress in the VR goggles as I went along. I also managed to add some fun things such as a scoreboard, fireworks, balloons, and a cheering crowd, but my biggest challenge came when I wanted to add a sumo wrestler goalkeeper.

I wanted him to move, but he wouldn’t, and I got a bit frustrated trying to figure it out. Eventually, I settled on making him static, but bigger, so the game could be a little bit more challenging.
Although this required a bit more effort it was so worth it: it was so much fun to be able to play a game I’d made myself, especially in virtual reality! How cool is that!
