Nice and cozy little exploring game! Wouldn't hurt to have the option to directly move into the other terrains without having to go back to the house all the time. 

You could make it linear and force the player into some platforming to reach the portals if you just want to have a "quick fix" on some gameplay for the player. Not saying it's needed though. 

Nice enviroments and FX but I was walking and then I falled in to a infinity loop falling

Really cool environments! It kind of feels like it has all the elements for a puzzle game, but it kind of lacks puzzles, maybe add a goal to the game or a way to make the exploring a bit more challenging.

Looks very good but I don't really see what the mechanic is here. Apart from the portals you can't really do anything. Maybe hide the portals a bit better too?

Maybe you can add objects to find so you can take them with to other portals? Maybe combining certain items in certain 'biomes' will cause a certain effect? Were you supposed to reach the house? If so, I couldn't really find a way to get there just yet. 

cool concept but there is little to none "gameplay".

I like that you could go around different environments using portals
