About Kosmolaris

Kosmolaris is a relaxing puzzle game where you'll have combine a wide variety of elements to create new ones, starting with four basic elements: Air 💨, Fire🔥, Earth 🍃 and Water 💧.Some elements are based on chemical principles, while others rely more on common sense or reverse engineering.There are two types of elements: Common and Special.

Common: These are public knowledge, and you can unlock all of them without any restrictions, just by applying chemical principles and common sense.
Special: These are mainly easter eggs, and unlocking them may require specific knowledge about certain topics. They often aren't real elements but come from fictional sources or iconic moments from our lives and the world at large (possibly).Don’t worry if you don’t find them—they aren't the main goal of the game. But if you're curious...

Some features:

6 languages for now: Spanish (Latam), Spanish (Spain), English, Italian, Portuguese and French.
Outstanding elements art!

+200 common elements.
+15 special elements (fiction, easter eggs).
+30 achievements.
Auto-save for each movement.
Relaxing background music.

✦ AI summary

Kosmolaris is a relaxing element-combining game with beautiful graphics and chill music that appeals to fans of the genre, though players note it lacks depth with limited objects and features compared to similar titles. The game draws criticism for being derivative of existing alchemy games and containing AI-generated content, which concerns some players about its originality and overall quality. Most reviewers seem to enjoy it as a casual experience but acknowledge it feels incomplete and would benefit from more development.

Many lazy "amateur" developers don't pay attention to their obligations under copyright law, and often steal the ideas of actual, real game developers without credit, such as the "developer" here has done. Putting aside the unethical intellectual, creative and moral bankruptcy of stealing someone else's game concept, this is also breaking that unwritten law of stealing other people's game ideas... you should at least try to do better than the game you're ripping off. "Kosmolaris" is considerably worse than Little Alchemy. Little Alchemy (famously ripped off by the Doodle God franchise) is a simple browser/mobile game where the player combines Earth, Air, Fire and Water elements to create new substances, which can then be combined to make more and more complex things... it's not that exciting after about an hour of mucking around. But this is not Little Alchemy... instead, someone STOLE the entire game conce…
