A downloadable game

August 2021 UPDATE:

Flynn is now releasing on September 15th, 2021! See the announcement trailer below.


This demo was removed as it's extremely outdated, and Flynn's release is coming up very soon! Please check out the game on Steam and check us out on Twitter for news on the release coming soon! https://store.steampowered.com/app/737520/Flynn_Son_of_Crimson/

Flynn: Son of Crimson is a handcrafted 2D action platformer that will take you on a journey of discovery and redemption.

Join Flynn in his beloved home of Rosantica - a beautiful island that was once ravaged by war and the oppressive presence of the now banished Scourge. The Scourge’s foreboding presence is seeping back into Rosantica, threatening the peace and freedom of the land. Accompanied by his mythical protector, whose Guardian Spirits have been stolen and must be reclaimed, Flynn will be tried and tested by the mighty Scourge and its powerful overlord. Will Flynn and his Crimson lineage be enough to put a final stop to the Scourge’s terror?

Key Features

Explore a beautiful hand-crafted world across unique regions each filled with ancient mysteries to be discovered.

Enter the sinister world of The Scourge to take on Zealock, Lord of the Scourge, and his mysterious dagger wielding warrior, Rozia; stopping them from taking over Rosantica at all costs.

Summon your mythical companion and protector, Dex, in times of need; requesting her help in crushing tough walls and slashing/biting her way through hordes of enemies.

Master the art of the Crimson energy that has been passed down from Flynn’s ancestors.

  • The Crimson Blade, a staple in Flynn’s arsenal, is the first weapon of Crimson energy gifted to Flynn by the Goddess Sorrell during a great time of need. Unlock piercing dashes and uppercuts to destroy those nasty foes.
  • The Crimson Axe demands precise timing and enemy prediction, trading the quick cuts of the crimson blade for a weighty windup. Use the axe to crush your enemy’s shields, and smash brittle walls to access new areas with brute force.
  • The Crimson Claws are a swift and energetic set of weapons used to stagger enemies with high attack speed and air superiority. Unleash your inner wildcat with unique wall jumping and spiral drill attacks to tear into enemies at a rapid pace.
  • Elemental Magic in the form of fire, ice, and lightning will be unlocked through a natural mutation with the flora of Rosantica.

Excelent short demo I enjoyed playing this one. I liked the music, the combat which reminded me of dark souls in a way. I liked the different weapon choices you can use. And I also liked the art style of this game. My husband liked it as well that he downloaded to check it out. Great work dev.

mano não estou achando o download, mas parece ser mt bom

Que lindo demo pedazo de mierda






Played this a few months ago. Felt very nice to handle, really promising demo. Liked the aesthetic and gameplay. Looking forward to anything new.


I think this game has lots of potential. With the combat, I would make the enemies attack while you're attacking them. If you did that the player would have to dash while attacking, then you could implement a combo system.


This has a lot of potential to be a great game, keep the good work! 


I'm really excited to see the complete game, the game has everything to be a success, great gameplay, beautiful graphics, but I hope the combat will be more difficult in the final version.

Awesome demo! While going the game I noticed while fullscreen on at 1440x810 results in a very slow fps playback but once I switch fullscreen off, the playback & fps is superb. Just thought to bring it up... Thx again! Love the soundtrack!

Hola, me encanta el juego, es muy bonito.

Sera también en Switch y PS4?


Awesome!! Doing a article for a brazilian website right now!

I havent even played this demo yet and i already love it. wow Thunderhorse, great game, keep it up, im proud of you!


I tried to make a speed run of the game, it was even interesting.

Just WOW. I knew by looking at the screenshots that this would be awesome. This is way, way, way beyond what I had hoped. 

Stunning to look at. Sound is beautiful. Gameplay is smooth. Cannot wait to play the full game. 

This is genuinely some pretty awesome stuff. I'm really looking forward to this game's release! One question, though. Any plans to possibly release this game on Mac in the future?

why do you own a mac

Kreegola Can't tell if you're joking or not

This game is so awesome! I played it for one minute and..WOW..i have no word to describe it. But I wanted something, I would like you to optimize the game for people who do not have the condition to have a good computer, because this game is very well and deserves to be played by all. Good game.


I am so happy that I got to play this demo and even more excited that it funded through kickstarter and has a page on Steam. I manage to play this for my Indie Game Showcase, and have already added it to my wishlist on Steam. I cannot wait for this game to come out.

Why's no one talking about this beautiful thing?

cos is a demo


Gave it a go...


Game looks so great! I made a gameplay video in spanish.

I love the game I hope the full version will come out soon
