I know what you mean by tedious and i think thats a lesson i learned (and i will finish to learn) when making test rooms 03 & 05 where i reuse the explosive cube as well. These cubes in fact are like the cherry bombs from Zelda.
Anyway, thanks for playing and you feedback ^^

I've been beta testing for another map creator (tmast98). About 30 minutes before I discovered your maps, I was suggesting ways to the creator a way explode through walls. Amazing to see you did it. That said, once per map is innovative. After doing it 6-7 times, it's pure tedium. Please don't take offense; I think it's a great idea, but it got used too much.
Difficulty: 4/10
Innovation: 10/10 (see caveat above)
Overall: 6/10
Thumb: Up

We need more puzzles with the demolition cubes... however, if I may make a suggestion, to the possibility of making the demolition cubes black and red, like the bombs?

I liked this one too. Exploding blocks - that's new for me. Very nice. Thanks again!

Interesting concept, but it got tedious quickly.

Yes! In theses maps a console command (r_portal_use_dlight 1) is sent. That makes your portals have a dynamic light which is a pretty nice, and doesn't hit performance.

Well that was very interesting - killed alot of turrets - the cube bomb is interesting concept. Is it me - or do the portals look different in your maps - I like the look. Thanks for making.
