glitch.com brings back memories of the pre-slack era Glitch MMO. What an amazing time that was, really beautiful game made by talented people, pivoted the communication side into what we now know as Slack
I did :) I made a browser-based MMO with Phoenix to test out liveview and learn the language: https://shopkeep.gg
And it was pretty annoying. Elixir doesn't really lend itself to vibe coding due to namespacing and aliasing of modules, pattern matching, all without static typing (I know, Dialyzer...). It also struggles to understand the difference between LiveComponents and LiveViews, where to send/handle messages between layers.
Without references to filenames, the agent perpetually decides "this doesn't exist, so I'll write it :)". I found it to be pretty challenging before figuring out I could force the agent to run `mix xref callers <Some.Module>` when trying to do cross-module refs.
Apotris (https://akouzoukos.com/apotris), a GBA "demake" of tetris is one of the cooler ones I've seen with regard to QOL. Lots of settings for tweaking controls and sensitivity that make it possible to fine tune the game to just feel fantastic to play
