Liked it! The controls are good and the art is nice, use of colors, etc. Game could definitely be expanded upon with enemies etc. I like the use of the portal mechanic, but when there are more than 2 in one screen it feels a bit random where you end up when you use one. And I think it would be better if it wasn't necessary to press A when you want to use a portal - it should transport you instantly without buttons press, I think. Also it wasn't always clear where you can walk and where not - readability could be better. But again: very good submission!
