Hi everyone! I had the idea for catcopter on my mind for a long time (got the domain ~13 years ago). It's a web multiplayer game where you can fly a dangerous cat and engage in competition with other players and critters (pterodactyls, chickens and angry penguins). I made it initially for me and my friends but it was quite fun so I thought I'll share it here too. The game is intentionally dorky and it was fun to develop. The tools I used were mostly Opus 5.5 (objects / rigging / motion), Tripo3d for some elements I struggled with and Fable for optimisation (cpu / networking). Backend physics are done with Rapier. Luckily I had a lot of elements / game dynamics done before from another project of mine (https://flat.social) so the actual iteration here took me around a week.
