I really liked the surprise ending, but I would have liked it better if you stuck to the story. Keplar aliens should return to Keplar to relaunch and get money from their own people. Also, are you going to tell me that all those auto miners and not one collects the coins for you. Plus, I would like to warn you that the flashing is an Epilepsy hazard.
Has great potential. Highly addicting. Suggestion #1. Zoom out when the world gets bigger so you know where the bombs are coming from. #2. Upgrades would be helpful. Life point or health upgrades, coin magnet, and defense. #3. Scoreboard for bragging points.
A lot of people love screensavers ;)
