Thanks, I'm glad you liked the game!
Thanks for your kind words. I'm working on a sequel for FoE but it's not nearly finished. I encourage you to start working on a similar game, it's fun to play with those mechanics and there is so much to explore. Here is another game you may like to try: https://geckoo1337.itch.io/project-a also there is Antichamber and soon (I hope) Magnifold Garden.
I already started trying to code something similar, and I think I know how to make the teleportation thing but I have absolutely no idea of how you did the many reflections thing that you can see in "The Tower". That really blew my mind. I mean, when you look at a door, you see what's in front of the other door. I mean, again, in the tower, instead of seeing a wall, you see what's in front of the exit door in the next floor. You'r game did that in a great way, so much that it feels real.
Gosh I have so many ideas!
And thank you for those recomendations! I really love these kinds of visual games, where you need to see the world in a different way in order for you to finnish them. I also recomend you the https://xra.itch.io/memory-of-a-broken-dimension game, which is really interesting and has a very cool dark ambience. And also try https://ianmaclarty.itch.io/forests-are-for-trees . All of his games are really strange optical illusion things.
You got me curious so I looked at asset from Unity Store and there is quite some:
There is free ones like https://assetstore.unity.com/packages/tools/particles-effects/gater-portals-system-59185
This one seems really great (but not free) and can play on scale (spoiler for FoE episode 2 ...), and there is a demo only
https://assetstore.unity.com/packages/tools/particles-effects/portalkit-pro-vr-a...
Even if you don't use Unity, it can be great for learning. I saw video of Memory of a Broken Dimension but did not know it was out, I need to try it!
I don't use Unity but yeah, it's always good to learn new things.
At the beginning I thought of making the teleportation stuff myself, but maybe I can use some assets too. Gosh I now want to make a game using these kinds of things so much I may start today (only maybe cause I'm sutdying right now. School is not easy and who knows if I got enough free time).
And Memory of a Broken Dimension is still just a demo and only has like 30-60 minutes of (awesome) gameplay. "This version is pretty old (2012) and not very representative of where the project is currently. " says the author, so apparently when it gets released it'llbe even better.
You can find the OST, as well as other tracks, on this page from Legulysse, the creator of the sound track. http://legulysse.free.fr/?page=audio
I will also add the OST to the itch.io page of FoE today.
