Keep up the good work! **Developer response:** Good luck! Our leaderboards can get really competitive! Keep on collecting -- we're going to introduce all sorts of cool powers & abilities for each of the Critters. You'll want to have as complete a collection as possible! ### 5/5 — Fun way to fight climate change! *2023-04-11* The game is loads of fun and seems to be improving with every update. Love the addition of collecting different little critters. Looking forward to seeing what new content comes next! **Developer response:** We love to hear that you're enjoying Hazel! A ton of time went into planning & designing the current Hazel Critters, and we're currently hard at work on Season 2! We'll also be releasing an update in a few days with new content, and a bigger update in a few weeks with new ways to upgrade & customize your Island.  Lots is happening with Hazel -- keep playing and tell your friends! ### 5/5 — Do a little something good *2023-03-28* What a great idea. Simple game, plant trees remove carbon in real life. What more could you ask of a mobile game? **Developer response:** Thank you so much -- we're glad you're loving Hazel!  Keep an eye on our "Projects" list in the app too. We're starting with tree planting projects, but we're working with our scientific advisory board (yeah, we have science advisors -- we take this stuff seriously!) to add more carbon-removal projects in coming weeks: regenerative farming, kelp sinking, engineered solutions... we plan to support a wide range of climate solutions.  But best of all, as a Hazel user, you'll be supporting all of them automatically! Tell your friends, keep playing Hazel, and let's help fight climate change together! ### 5/5 — awesome and feels good *2023-02-23* i love it **Developer response:** Thank you! We love having you as a user! ### 5/5 — Love the characters *2023-02-23* Excited to see the gameplay expand and adapt!! **Developer response:** We've got all sorts of cool gameplay & new art -- new Critters, new items, etc -- planned! Can't wait to see what you think about it! ### 5/5 — Love the new game! *2023-02-23, version 2.8* Love collecting Hazel Critters! Super fun. Now I just have to get to the top of the leaderboard ### 5/5 — Cute critters *2023-02-23* The animals that hatch from the eggs are so cute. I love their names and back stories. Milkshake is my favorite. **Developer response:** Thank you for your feedback -- we're glad you love Hazel! Stay tuned for even more exciting updates over the coming weeks! ### 5/5 — Great climate change app!! *2022-01-28* I have been looking for a way to help with our climate issues in an every day way because I’ve always felt so helpless. This app has allowed me to contribute and make an impact in my daily life on the reversal of climate change! Highly recommend this app! **Developer response:** Thank you! Our hope is to give you a fun, easy way to have an impact -- just by playing the game! Keep it up -- you and thousands of others all around the world are making a big impact! ### 5/5 — Already great, keeps getting better *2021-12-20* The climate news is abysmal. Is feels great to use a product that lets me make a positive impact by essentially buying carbon offsets. The app also lets users see the company’s impact as projects are funded. The developers are consistently making improvements too. There’s a “gamification” aspect that’s optional, which is nice. **Developer response:** Thank you for your kind words -- and trying Hazel! We want to make Hazel something you love using to have an impact on climate change. Look for some exciting new features coming up, and please let us know how we're doing! ## Frequently asked questions about Hazel ### How does Hazel help fight climate change?
