Cool game! I liked the puzzly aspect of trying to make a route to get all the coins, through the portals and the boxes. First attempt I got stuck at the end without all the coins, and then my second play through I had to be more thoughtful. I think the spikes we're a little bit frustrating to me - they we're more a nuisance than an actual obstacle, because they didn't actually kill me. I also think it would be nice if there was some indication of where a portal was going to take you, as it was a little bit trial and error. Graphics were clean, and sound effects + music definitely added to the experience - I think the coin sound is a bit too loud though, I had to turn everything down because picking up coins was so abrasive. Would love to see more levels and mechanics :)
