New puzzle game : Petris

Hey All,

Edit: ** Updated version, see below in thread**

I've been working on a new puzzle game. It's about half done but in a very playable state now, so I thought I'd share it's progress. Feedback is welcome.

The concept is pretty simple and Tetris/Dr. Mario-like. Build pets and keep the board clear. You can earn some extras (score bonus, special pieces) by building longer pets. Standard Head-to-Tail works, so do things like tail-to-tail/head-to-head.

* The different game types are not yet implemented (aside from Marathon)
* Music is the hardest for me, so it'll probably be left until the end of development
* Lots of small polish and extras remain to be completed

Does anyone know of existing games closely share the concept? My knowledge of puzzles games is fairly limited. I've found one somewhat similar game: Pipetris

Awesome! I played it for a bit and am eager to see what you do with it in the future.

Re: New puzzle game : Petris

it might be fun to see the gallery of the most weird pets you have "built" at the end. shouldn't blocks move down somehow, as in tetris? for example, if, after disposing a pet, a complete empty row appears?

That's a fun idea. smile

I had originally planned for blocks to fall once no longer supported from below, and may still. However, I also realized it could leave many pet blocks inaccessible/less accessible after they shifted down, which could be frustrating in gameplay. On the other hand, allowing blocks to fall could allow for combos if done right (like in Dr. Mario). It's gonna require more thought.

my idea was to move blocks down only if a complete row becomes empty. blocks never move vertically one relative to the other.

another approach is to move "figures". if you connect two parts of a spiece (fish-to-fish, cat-to-cat) together in a right way, they become a "figure", which moves as a single piece only. and if it is not supported anywhere.

Re: New puzzle game : Petris

It's been a little while so here's an update. The game is getting fairly close to a released state. There are a couple more things I'd like to tinker with and some extras I'd like to try out, but it's feeling much more complete. I think most of the glitches are fixed too. smile

You can play it on itch.io, or download the ROM from that page or the github page:
https://bbbbbr.itch.io/petris
https://github.com/bbbbbr/Petris


Here are some of the updates...

There are now four modes which encourage different styles of gameplay:
* Long Pet
* Tail Cleanup
* Level Up
* Marathon

Added five difficulty levels: Easy / Normal / Hard / Expert / Beast

There are three sound track options (courtesy of GB Studio community assets)

A couple high-contrast options for the pet tiles when playing on hardware that hasn't had a backlight mod. (These still need a little tuning to improve the contrast between blue and green I think)

Re: New puzzle game : Petris

Getting closer to finished with Petris

Here are some of the latest changes:

* Added a game play mode: Crunch-up (board shifts up and new pieces appear on bottom every N seconds)

* 2 Player versus over serial link cable (any game mode, synchronized pieces, send crunch-ups to opponent by completing long pets and level-ups)

* Different scenery color schemes every 5 levels and color palette-to-palette fades

* Cartridge sticker art (initial version)

Re: New puzzle game : Petris

Loving this, reminds me games like Baku Baku Animal and Wild Snake.
Looking forward to seeing the final version.

Re: New puzzle game : Petris

I hadn't seen Wild Snake before, thanks for mentioning those! The look is very similar even though the gameplay ends up being different.

Those falling whole-snakes remind me that I'd thought about dropping pieces of multiple body segments on the board instead of single segment at a time. But it would add more complexity to the game play that I'm not sure is useful and it already gets hard enough at times.

There is still plenty of RAM left, so it might just happen. Esp since there isn't anything significant left on the to-do list.
