A nice, simplistic clicker. I enjoyed the variety of available upgrades and the achievements encouraging the player to explore their options. As all good clicker games, it had this addictive factor when the numbers finally start increasing rapidly and getting the fancy stuff becomes viable. Also, I found the art style very entertaining. What I would add for a complete experience are sounds/music and more visual additions, to make the game feel more rewarding and satisfying. Great work, thanks for sharing!
