Cool. I've been teaching myself Python programming my Anki Vector robot (and will be doing so for Cozmo in the future) so a python like language sounds interesting. I thought I read about drawbacks of Python for game development but I'm not sure. I think it related to how far removed from machine language it is compared to more complex / harder languages and that has some effect but I'm not sure. It might only matter for certain types of games anyway. If the game engine itself isn't made with the Python like language, maybe those drawbacks don't apply for the code used to make a game within it using the editor though as if the game engine is doing the heavy lifting, maybe it doesn't matter. I know more about programming in general than how game engines interact with user code etc so I'm not sure about all that.

I have a feeling I looked at Tiled myself during one of the game jams on Steem. I just looked at Phaser and that looks interesting too. I hope it all worked well for you.
