During level generation, I usually set walls/floors to "1", and then pad things out around those 1's.

Yesterday, I struggled to figure out why enemy placements were so very few and far between, until I realised that I was randomising the floor tiles between 1 and 6.
The enemies were only appearing atop the rare 1 floor tiles.
*tsk* silly me.

Today I need to rejig that quite a bit, as the sudden influx of enemy placements has made the game completely unplayable!!
Oops.

I might even have to change the weapon bullet speeds, as the slower Hard Mode bullets are now filling up the screen entirely.

But I'm definitely getting closer to things being a bit more fun.

I hope.
