I like the overall idea for the game, however the random bubbles that pop up after done merges, should be sellable to free up space as compared to the timer they use. Also the different goals should have more attainable materials, such a gloves. I can burn through all of my energy 2 or 3 times before making one set of gloves, and i need to make at least 3 sets. I love the rest of the game however. Great job.
