General tips

• For repeated expensive drawing options, such as drawing a rotated sprite or a large amount of text, it's a good idea to cache the result to an image once and draw that repeatedly instead.
• Audio formats in order of decode speed, fastest to slowest: 16-bit pcm wav, 8-bit pcm wav, adpcm, mp3.
• The Playdate's audio sample rate is 44100, but if you're experiencing lag when playing audio at that rate, you can try halving the rate to 22050.

C tips

• The Playdate has a weak CPU but a comparatively generous amount of memory. Favour memory-based optimisation techniques, such as lookup tables.
• Where possible, move branch statements outside of loops, even if it means duplicating the code for the loop. (probably applies to Lua too?)
• If you need to parse a binary file, use playdate->file->seek to jump to the parts you need and playdate->file->read to only read the data you want. Try to avoid memcpy-ing the whole file to memory in one go.
• If you're blitting to the frame buffer and need to ap
