Shortly after noticing someone did a video playthrough of the last Unity game I built, I noticed that another giantess game in Unity was recently released. It's called "Sizebox", and as far as giantess games go, it's a godsend. Admittedly it's a fair bit more advanced than the one I built, although the features are similar. I've tried it, and it's remarkable.
The game allows you to create a giantess scenario using premade NPCs and levels, and program them to perform certain actions with the player. You can command a giantess to grab you, step on you, chase you, and quite a bit more. You can also change their size as well as your own, and fly around them as you see fit.
The best part is that if you have an MMD model, you can actually put it into the game! I have a few MMD models I did this with and it worked really well. Not to mention it has VR support, which is a perk if you've got an $800 headset.
I very highly recommend trying this game, it's the best thing to happen to t
