The demo game Jelpi (by Zep) can be completed in 8.2 seconds!

It's just a first attempt at this, so the code is pretty terrible (7th tab if you want to see it).
This was all hand-coded over about less than an hour, so it's in no way perfect.

What is a TAS though?

A TAS, or Tool Assisted Speedrun, is when a human writes all the inputs for a computer to perform.
This can be used to create theoretical "perfect" speedruns of games.

Well, have fun messing around with this to finish the 3rd level and/or make this one faster.

I have created a simple PCM audio visualiser while experimenting with PCM.

It:

Has three different waveforms:
- Square
- Sine
- Harmonic
Visualises the audio output
Shows the formula for calculating the wave
Allows adjustments to
- Volume
- Frequency / Pitch

I hope that this helps!

Planning on making a simple way to play sound effects too. Have a nice day!

Breaking Pico-8's colour palette

A simple way to break Pico-8's palette.

Changing the screen palette using poke(0x5f2e, 1) and then changing the red or dark red / purple colours, then running, exiting, and going to the sprite tab results in the above image. The red and dark red colours get paled in by Pico-8.

Thought it would be an interesting first topic. Have a good day!
