Dev Updates & Bits

Hey all! This update took bit longer than I wanted - I’m working a lot, but less on MSA than I wish these days, I’m grinding to get things organized and wrapped up before the year ends.

Well, now you can save some decks and track how they’re performing over time. Each saved deck comes with some basic stats (wins, losses and win rate) so you can follow its evolution. Seems a small change on surface, but is base for all the metric tracing Im planing for the upcoming ranked mode!

I also pushed a few layout and text improvements and fixed two card issues that were reported recently - thanks to everyone who pointed them on out Bug Report Thread!

Next steps: Ranked queue and Dark mode! Please comment your thougts and what you are waiting for future releases!

As always, a massive THANK YOU to everyone playing, reporting bugs, and sharing feedback. And a special shout-out to all Patreon Supporters who make continuous development possible.

Cheers, Doug - dev & wannabe Kamen Rider!

Hey all! Yesterday’s update brings a handful of small but meaningful improvements to keep the site smoother and stable. Here what changed:

Server & Performance Tweaks - Minor adjustments on the backend to improve stability and monitoring, helping the servers run easy specially during peak hours.

Gundam Epyon fix - I corrected an issue where Gundam Epyon wasn’t automatically triggering its effect when it was already Active (yes, I know... is sad, but this is the correct behavior).

New option for always Show resources and cards counters.

UI and stability polish - A few small interface improvements and subtle stability fixes were applied across the game.

I also want to send a huge THANK YOU to everyone playing, reporting bugs, and sharing feedback - you’re helping MSA improve every single day. And a very special shout-out to all Patreon Supporters who make ongoing development possible. You’re amazing.

Cheers, Doug - dev & red button pusher!
