I've posted this on reddit back in the day, both on r/tipofmytongue and r/tipofmyjoystick.
There was a free indie game that I installed on my Windows PC back in the 2000s. I don't know where I got it, but I don't think it was Steam. The game was a 2D platformer where the main character was I think a red cat. I remember it being kind of fast paced, and you had a sword, and at one point can shoot lasers or something which played into the platforming (I think charging it and shooting it downwards gave you like a double jump? I'm not 100% sure if this is accurate).
I've tried so hard to find this game again, but time and time again I've come up empty.
Some more details, though it's very foggy at this point:
- I think there was a level select screen, kinda similar to like Mario 3
- There is the typical friendly village level where you can talk to NPCs
- I think one level was on top of a train.
- It may not even be a cat, but I always thought it looked like one.
- The game was a digital download, pretty sure I got it from an indie game dev's website showcasing his games and projects, and I'm not 100% sure the game was finished.
