A Koopa’s Revenge Gold

A Koopa’s Revenge Demo #3

I uploaded another demo of A Koopa’s Revenge Gold. Link above.

It’s not a huge update. Much of the work went into making it 60fps, and accounting for the change. But two new levels are playable.

Notable Changes:

• Framerate increased from 40fps to 60fps.
• New (placeholder) map screen.
• Entirely mouseless gameplay.
• Prerendered some graphics to improve performance.
• Backgrounds recoded and prerendered to be more efficient when scrolling.
• Updated collision detection for terrain and blocks.
• New and updated backgrounds.
• Levels 2-2 and 3-1 are playable.
• Mario babies changed to balloons.
• Level-complete and death screens updated to chalkboard look. (Still incomplete)
• Functioning warp pipes.
• Player turning animation.
• Framerate counter.
• Feathers float down properly instead of acting like fireflowers.
• Added four frames of coyote time.

Known bug: You can’t run over one-tile-wide gaps. I changed the collisions to accommodate the new framerate and fix some bugs, but this new bug appeared as a side effect. I will have it fixed for the next demo.

EDIT: I fixed that bug, and uploaded the fixed version of the demo.

Not looking for any specific feedback this time. Just felt like sharing. Feel free to Let’s Play or stream it, if you feel inclined.

I’ve dug up the ancient prototype versions of AKR1 from 2004/2005. For those of you on mobile, here’s a video of them:

For those on old people computers, here are the playable Flash versions:
Older Version Using Pixel Art
Newer Version Using Vector Art

There are two versions, one with pixel art borrowed from various games and no sfx, and another traced vector art based version that includes the first boss, Wario. Both versions are a lot clunkier than the published game and are presented in glorious 15 frames-per-second.

Why did I cancel this build and start over? Aside from the apparent clunkiness, the performance was terrible. Every block you see (including the ground blocks) is constantly running four different collisions against the player. That doesn’t sound like a big deal in current year, but back in 2005, when I scrapped it, the programming was painfully inefficient and it ran at even less than 15fps.

In other news, progress on A Koopa’s Revenge Gold continues. I’ve upgraded the game from 40fps to 60fps (long story) and am making progress on rebuilding the levels.

After a few weeks of work, I finally have A Koopa’s Revenge Gold at about the same state of completion it was at when I first showed it off almost three years ago. But at least the tedious part is over.

I’ve got the first two levels mostly done, and at this point I’d like to get some feedback on Koopa’s movement before I get to far into development. I’m trying to strike a balance between the original game’s movement, and the ideal movement, so that it still feels like the same game, but not so dated.

I’ve been toying with the idea for a while now, and I’m making it official. The game project previously known as A Koopa’s Revenge Anniversary Edition will now be called A Koopa’s Revenge Gold.

I missed the ten year anniversary, so I decided a name change was in order. Anniversary edition is a bit of a mouthful anyway. I want it big and sparkly and GOLD.

The logo is temporary. I’ll have a fancier, more refined logo when the game is done.
