Thanks for the motivation
No no no no, that lasers room is actually "super" easy!! I guess it looks scarier than it actually is. It's just 2 alternating beams, and the spiky blocks move slowly... I can make it fine 8 times out of ten. I'm gonna reconsider the leaves room though, maybe using some other "scanned leaves" tileset with different colors...
The idea of using the original game's graphics seemed more like a job than a hobby. I just like to play around with tilesets. Although I'm actually making one or two 'sets for the metroid stuff I can't find a replacement for.
