Frogger 🐸 Use dpad to move. Go right to next level. #game

u/tomxor

Nice, moar games!
u/KilledByAPixel

Thanks! Full screen recommended, each level gets a bit faster.
u/tomxor

Got to level 8, pretty hard throw Z-2. Only issue is that difficulty is slightly tied to OS key repeat delay and rate. But keyup is not fitting in here so I don't see a solution.
u/jdspugh

Star pulse #sphere

u/deobfuscate

I cannot explain with words how cool this is.
u/donbright

if i undersand it, the "twinkling" really adds alot. they aren't all the same size of white particle?
u/rodrigo.siqueira

The "twinkling" is given by the particle size (2 last parameters of x.clearRect). Pixel size is defined by 3*S(i)+1, so it's between "3+1" and "-3+1" and the "i" makes it almost random for each pixel. An extra twinkling effect could be made by adding "t", but I thought it would be too exaggerated. You can try by changing to: K=5*S(i+t*4)
