I'm really glad you enjoyed it, thanks for the post. I'm not very profit motivated so lack of sales doesn't matter to me, but real life slowed things down. I'm idly working on something like Simtower on crack, but it will take many years I think. Maybe I'll add some bonus levels to Blast-Axis for my hardcore fans like you. I'll make sure to post an announcement here and on Steam when/if anything happens.
