I was making some art for my upcoming game but I decided to make a mech theme instead and gave up on this work while it was early. It isn't very detailed because of that.

The portal look like a window to outside on the preview, should have used another colour to distinguish :) It was going to be a clear the room, move onto the next by using portals type of game. And I probably should've made the characters to step middle of the tile :)

Hope you can make use of these or it inspires you for something else :)

Was inspired by Calciumtrice's Dungeon tileset.
