Awesome puzzler you've made here! Love the really smooth and professional design you have to your games where everything just feels great and flows so well, both in a graphical sense and the way the game mechanics are intuitively introduced through the UI and the level design. Could maybe use a bit more of an intro or intermissions in the game to let you know of the setting and other things as it does have a bit of a 'lonely' feel to it at times (though that may be intentional due to the space/Mars theme). Anyway: this is top shelf stuff! Also, while its not related to the game, I appreciate the insight you provide in the game design through your posts and would love to hear more!
