I liked the idea of this! Do you have a link or any info on your GBA version of this?
It's easy to get caught between two close together ghosts when coming down from one's power pill, I find. Perhaps I just haven't got a knack for this yet?
I had to dig up the file - I uploaded the Falling Ghosts Game Boy Advance version to Dropbox.
There are some noticeable game play differences from the CHIP8 version:
In the CHIP 8 version, I agree that the "cool down" period of the power pill is short and it is easy to get snagged by the ghosts. I think the game is beatable, but I have not done so yet myself... I'm curious if anyone does get to 256 points :)
