Hello! I'm the developer of MEGAKO☆PUNCHI! 🎉
<Hello!
I started making MEGAKO PUNCHI because I wanted a satisfying single-player card game that captures that wonderful feeling of "getting away with something" that only card games can provide.
In addition to the satisfaction of hitting your cost target exactly—built around a Blackjack-inspired system—I hope you'll discover things like:
"Wait, this item works like THAT?"
"This combo might be ridiculously strong!"
(Card game fans might find quite a few tricks hidden away... 🥳)
Since it can sometimes be hard to tell whether something is a bug or a feature, please don't hesitate to send feedback if you encounter something suspicious!

The demo is completely free, so give it a try! If you find an especially fun or overpowered combo, I'd love to hear about it in a review or on X (formerly Twitter).
(If you post on X, please use the hashtag #必殺メガ子パンチ so I can check it out!)
Leading up to the full release, I'll be replacing temporary artwork and adding new cards and items.
(After all, discovering new card combinations is the most exciting part!)
Since development is still ongoing, some cards and interactions may change before release.
You might even discover a combo that's only possible in the demo version...!
The full version will also include a high-difficulty mode called "Endless"!
In Endless Mode, you'll face randomly generated enemies and make use of a new "Modification" system that allows you to upgrade cards in your deck.
(Updated: 2026/07/29) This system didn't mesh well with Endless Mode, so its implementation has been postponed for now. Instead, Endless Mode features enemy special abilities, reduced maximum Energy, and HP carrying over between battles.
The current target is Summer–Fall 2026.
I'm aiming to release updates about once a week, although development of high-difficulty content may occasionally slow down the update schedule.
I'd also like players to get a small taste of the harder content, so Stage 1 of the high-difficulty mode might make its way into the demo... maybe?
The demo is participating in Steam Next Fest!
Steam Next Fest is a special event where players can try demos for a huge variety of upcoming games.
(The MegaKo Punch demo will remain available even after Steam Next Fest ends.)
