Now you are on thin ice and just want to get back to your friend on the shore.</p> <h3>Game Play</h3> <p>Control your skates with the left and right buttons. Alternate left and right to speed up. Hold to turn. You haven't exactly learned to stop yet, but if you start turning circles, you will eventually slow down. You can walk on the snow, but it is very slow.</p> <h3>Credits:</h3> <p>Music composed by Vince Guaraldi<br /> <em>Christmas Time Is Here</em> arranged by <a href="https://www.lexaloffle.com/bbs/?uid=11292"> @Gruber</a><br /> 3d effects: <a href="https://www.lexaloffle.com/bbs/?uid=39676"> @Mot</a>'s <a href="https://www.lexaloffle.com/bbs/?tid=37982">Instant 3d Plus Library</a><br /> Special thanks to <a href="https://www.lexaloffle.com/bbs/?uid=32135"> @thattomhall</a> for advice on the ending<br /> Everything else by <a href="https://www.lexaloffle.com/bbs/?uid=49583"> @bikibird</a></p> <p>Created for the <a href="https://www.lexaloffle.com/bbs/?tid=50644">2022 Advent Calendar</a></p> https://www.lexaloffle.com/bbs/?tid=50699 https://www.lexaloffle.com/bbs/?tid=50699 Sun, 18 Dec 2022 05:05:51 UTC Santa Scouts <p> <table><tr><td> <a href="/bbs/?pid=122456#p"> <img src="/bbs/thumbs/pico8_santascouts-5.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=122456#p"> Santa Scouts</a><br><br> by <a href="/bbs/?uid=49583"> bikibird</a> <br><br><br> <a href="/bbs/?pid=122456#p"> [Click to Play]</a> </td></tr></table> </p> <p>This is the year you find out if Santa is really real.

You should make it home in under 5 minutes. Don't fall off.</p> <p>Your teammates can help block the opponents and you can set their overall direction and confrontation style in the strategy session.</p> <p>If you are using a keyboard to play, use the X key to advance to the next screen/teammate and the Z key to switch modes in the strategy session. Arrow keys select options, set direction, and move teammates.</p> <p>The visiting team's strategy is randomly generated, but set for a single day. Learn their strategy over multiple plays and eventually defeat them in a single down!

I used the midpoint circle algorithm to calculate the edges of the iris. This algo avoids trig and square root functions and so is super fast. Even at 60 frames a second, there's no lag. I decided to make a more generalized version, implemented as a coroutine. I hope you find it useful for your projects.</p> <p>To use: </p> <ul> <li> <p>Copy the iris function from the cartridge above into your own cartridge.</p> </li> <li> <p>When it's time for a transition, assign the coroutine to a variable in your update function: <code>effect = cocreate(iris)</code></p> </li> <li>In the draw function, call the coroutine: <code>coresume(effect, 1, 128, 1, 15)</code></li> </ul> <p>The parameters for the coroutine are starting radius, ending radius, step, and color. A positive step indicates by how much to open the iris on each frame. A negative step indicates a shrinking iris. See the code for examples.</p> https://www.lexaloffle.com/bbs/?tid=42919 https://www.lexaloffle.com/bbs/?tid=42919 Sun, 16 May 2021 23:58:15 UTC Ice Cream Clouds <p> <table><tr><td> <a href="/bbs/?pid=90911#p"> <img src="/bbs/thumbs/pico8_icecreamclouds-1.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=90911#p"> Ice Cream Clouds</a><br><br> by <a href="/bbs/?uid=49583"> bikibird</a> <br><br><br> <a href="/bbs/?pid=90911#p"> [Click to Play]</a> </td></tr></table> </p> <p>Straight from the laboratory of Professor von Stroopwafel is a modest proposal to solve global climate change.

Entered in Toy Box Jam 2020.</p> <p>Tis the season to sing carols, drink nog, and decorate the night with Christmas sneks. </p> <p>Press an arrow key to change the direction of the snek and connect bulbs to the live wire at the front of the snek to light them up. Build a long snek or a short snek. Ride the high speed rail to get around faster.</p> <p>This is a mellow game with no set goals, but beware! If you touch the live wire to the snek you will create a short circuit!</p> <p>When you are happy with your snek, press X to go to the forest and plant a tree decorated with your snek. Then go build another snek so you can plant another tree. </p> <p>Merry Christmas and may 2021 bring you only good things.</p> https://www.lexaloffle.com/bbs/?tid=40926 https://www.lexaloffle.com/bbs/?tid=40926 Fri, 25 Dec 2020 20:17:53 UTC
