Really neat game, the difficulty of the waves was pitched just right and it kept me coming back for a good number of tries to see if I could beat my last score. The art is really nice too, especially the flying sprites. The only small change I'd make would be to darken the rest of the map, maybe even completely, to make it clearer where the limits of your lantern are. Having it green with details visible kind of tricked my brain into thinking I should be able to see things in areas where I couldn't. That's a small point though - the lantern mechanic still worked really well and made for some nicely twitchy gameplay!
