Evaluation
CATASS is a free-to-play casual game released on June 23, 2023 by a solo developer. The store description makes clear this is a personal passion project built entirely by one person in their spare time, with the explicit goal of proving they could develop a solo game from scratch. The description presents the game as a complete experience: it has a main storyline to complete, achievements to unlock, and a defined goal (becoming "the greatest cat of all time"). There is no mention of planned updates, future content, DLC, or seasonal additions — the framing is entirely that of a finished product players can pick up and complete. No developer news posts exist on Steam, and no DLC has been listed. Given the solo hobbyist nature of the project and the store description's framing of it as a self-contained experience, the game appears to have launched as a complete package.

About this game
CATASS is a game where you are a cat! Never let your human realize your feline plans. THROW THINGS! And many other important plans, of course. I mean... Meow.
Complete the main storyline to declare yourself a supreme cat and show your human who's in charge. CATASS is a casual game where you can demonstrate your worth as a cat through different levels and extra challenges.
An adventure filled with exciting levels, puzzles, riddles, humor, references to pop culture, and the internet.
Complete all the achievements to become the greatest cat of all time and crown yourself as the master and supreme ruler of CATASS.
CATASS is a personal project developed solo and made in my free time on weekends. And to provide a fun and exciting experience. This project is to prove myself by developing a solo game from scratch: Game design, graphics, logic, music, and animations. I've made everything except the sound effects and typography I bought in Envato Elements.
If you play the game, I beg your pardon because of all the bugs. I'm not a programmer and an absolute noob developing. Surprisingly, many great people have finished the game, streamers, VTubers, and amazing gamers around the globe. The game works. IT WORKS! I really don't know how, but it works!
Download CATASS now and experience the thrill of being a cat. You won't regret it!
