Day 3: Juni's Challenge

We asked our discord which challenge courses were their most favourite and least favourite... surprisingly Juni's Challenge was a favourite of many!

We're doing a Rusted Moss advent calendar over on our discord. The themes are influenced by how our community responded in a survey we posted. We also share some fun Rusted Moss stats over on our discord for each day related to the theme...

Another little set piece that was cut due to not fitting in flow wise. It was super cool though...

Overgrown version of that winter update experiment. Did not end up getting used because the art style didn't fit with the rest of the game.

This was another unused experiment from our winter update. It didn't quite fit into the art style of the rest of the game.

Been going through some old folders recently so here's another unused concept from our winter update!

Scrapped experiment from the RM winter update.

Happy Halloween! 🎃

We posted a fix for Ameli controller rebindings and previously had hopefully patched up the memory leaks some people were experiencing.

Because halloween, we also pushed a silly little change for just today. (Not a content update or a new character. Just something small!)

Our momentum-based metroidvania is creativity gated! Solve the same platforming puzzle in many different ways... (#5 is my favourite cause of how goofy it is).

Currently 50% off on Steam!

We don't have a dash in our metroidvania but we do have gun recoil and a grappling hook.

Our character's turn around animation. Small polish can be really satisfying (:

How we did procedural 2D animation for Rusted Moss

Actually our 2D pixel art metroidvania is 3D.

Our metroidvania has no double jump or dash but prob has some of the most expressive grappling hook movement you'll find!

Palette editor mod made by one of our players!! It's been really awesome seeing the mods our players have created.

Some sprite stacking stuff Emlise had worked on before Rusted Moss!

In Rusted Moss, Fern was also animated with procedural animation but you can see with a side scroller in mind.

No hate to people that dislike our game (wasn't made for everybody!) but we got a recent negative review that was pretty funny and made us laugh.

Rusted Moss multiplayer is now possible??
Harlem512 has created a mod that lets you play Rusted Moss with friends!

Mind blowing the kind of black magic that has been possible.
