Evaluation

JASEM launched into full release on October 19, 2017, following a period in Early Access. The developer's release post on that date explicitly stated "JASEM is completely and totally released!" and summarized all the content added during Early Access — new levels, a boss, an enemy, a music track, and bug fixes. A handful of small patches followed in the days immediately after launch (localization, bug fixes, minor gameplay tweaks), but the last substantive communication about JASEM itself was in late October 2017. The only DLC ever released was the game's soundtrack, which came out on October 5, 2017, before the full launch. After wrapping up JASEM, the developer moved on to other projects: Save One More (released May 2018) and Katana Kata (entered Early Access January 2020). There are no unreleased DLC entries, no announced future content for JASEM, and no post-launch update pattern beyond immediate post-release polish. The game launched as a complete, self-contained product and has remained that way.

About this game

Do you need any reason to shoot your enemies in game? Because JASEM doesn't give you one - just you, your weapons, crazy beats and enemies. And you need to shoot every one of them, and it's up to you to make it the most hilarious and explosive way.

So, JASEM: Just Another Shooter With Electronic music - is:

Whirlwind gameplay;
Gunfight non-stop;
Fighting enemies, no dancing around their slow bullets;
Juicy low-poly effects;
Crazy physics - you can do improvized stealth or create shortcuts;
Epic Bosses;
No story, narrative and even texts at all (except of seizure warning, because, you know, if you know the way of warning about it with no text, pls let me know).

Taking into account the last item, here is the perfect place for game credits:

Game design, programming, bugs creation and a lot of stuff you don't want to know about - Stas Shostak;
Music: Ira Lobanok;
3D-models: Aleksandr Palmov;
