NecroFactory
A downloadable game for Windows and Linux
Your regiciding brother has killed you! Fortunately with a witch's poison that turned you into a lich... and you know what, being dead and not having to be king any more is actually kind of great - lots of time to tend to your bergonias! If only he hadn't found out and sent guards to trample your flowers. Now its time to build your strength in the only way a powerful lich does - waging war by creating a factory line of undead!
NecroFactory is a traditional roguelike with elements of tower defence and factory building. In order to make your way though, you must set up small factories to raise undead and then kill them with your defences, with the goal of creating better equipment and stronger killing lines.
This game was made inside one full week for the 7 Day Roguelike Challenge of 2025. Per the rules, this game wasn't completely from scratch - I build upon the foundations of my many previous 7DRL entries. This is my 17th entry in this challenge!

Played for a while, though part of that was just to figure out how to play.
I really like this one! I beat it once the intended way and almost twice by rushing the boss, but I made a mistake at the end. Could use some balancing. Please make it so you can move when building with the mouse lol, even if just adding WASD keys for that. I had one crash to desktop that caused me to restart.
Adding a time element may help, say waves of reinforcements from the castle, otherwise I just sit and amass resources and spam turrets. I'm convinced that you can beat the game with just spamming the first chomper turret. Adding enemy resistances could fix that.
Oh, and allow skipping the whole intro! It's nice but I don't need to see it again on my 5th death :)
Agree that there's definitely a lot of potential here, with room for improvements - but still sounds like it hooked you which is great! Thanks for playing, glad you enjoyed it!
Game wont start up for me

This is a shader compilation issue that only seems to affect Linux users, should be fixed in latest version!
i cant download the new version, it doesnt show for me.
Sorry, I understand I might have caused some confusion with this, but I revised the versioning so v2->v1.1, v3->v1.2, newest version v1.3
i can only download V1.0 (exe) and already have V1.0 (jar)
I had fun with this. I'm a sucker for factory sims. Impressive amount of polish and depth. Well done!
Thanks for playing, that's a boss killer all right!
And with V2 game crashes on death.

Many thanks again, fixed for V3! This was present in the original version too, but doesn't happen every time - it was caused by receiving resources after death
A bit unexpected twist, feels hardcore at beginning(mostly from non refundable bulldozing), but very cool like almost all your game!
But warning: by clicking+skip-turn too fast I got crash...

Hello many thanks for reporting! Fixed and fixed!
You captioned fix as post challenge, but JAM still accepts edit aren't?
I like game, and it's a bit sad to me, to see so important fixes as postjam...
Thanks for the support! unfortunately my slot is closed. The rules give 7 days to do the job, where you can start whenever you want on the first weekend, and finish the same time on the next weekend - the jam on itch stays open to accept entries from later starters in late timzones. It's all good though - from past experience I know people play the bug fix version anyway.
I overestimate final boss a bit... And prepare a lot of h-kits and turrets before throne room...
Soo tasty but so small... I already wait for next year...
