Mr. Luwak — the mentor
A coffee shop management and idle tycoon game. Grind, brew and serve your first cups, then upgrade equipment, arrange supplier deliveries and hire staff to automate. Staff the counter to unlock offline earnings, and grow from a coffee cart in Warsaw to cafés in Tokyo and New York. Mr. Luwak shows you the ropes.
HappyTooth is a one-person indie studio, founded in 2025 and based in Poland, that builds playful, polished mobile apps and games for iOS and Android. Design, code, art direction and support are all handled by founder Andrei Karavaichyk, which is why the studio ships one app at a time rather than several at once.
Two titles are published so far. Ticko: Tooth Brushing Timer turns two minutes of brushing into a game for children aged 3 to 9, with cartoon episodes, daily streaks and treasure chests, and carries no ads. Tapuchino: Idle Cafe Tycoon starts with hands-on coffee making, then lets you hire staff, automate your café and expand to other cities. Both apps support 23 languages. Both are still in active development, and every bug report reaches the person who wrote the code: happy.toothapp@gmail.com.
