Short level, I beat it in about 10 minutes, but it was a lot of fun while it lasted!

Even if you ignore the limitations under which this was made, this is a great little map. Gameplay is well balanced and monster placement is effective and feels natural. Progression is clear without feeling forced and makes perfect sense in context: yes, you have to find and press buttons, but they all serve a narrative purpose.

The roof texture as you enter is strangely low-res and sadly (yet in this instance understandably) there are no secrets. Overall this lacks the impact of some more epic releases, but it is – barring the lack of secrets – a near-perfect example of what a small map should be.

Thanks to its great texturing, this feels a lot like a Quake 2 map playable with Quake monsters and weapons. Unlocking those access levels which release new waves of enemies is fun. Backtracking is avoided as much as possible, balancing is well done, gameflow is perfect. Maybe it's a bit short, but this way it feels like a compact, focussed and straight-forward experience. Thumbs up!

A truly astonishing experience, and surely the best 100-brush map of all time. (I know it won the 100b competition it was in, but to me it seems head and shoulders above the winners of the other 100b competitions, too.) Feels absolutely solid.

Incredible what was done with the limitations at play. Perfect flow and nice to look at to boot!

fun to play. Maybe throw in some secrets to encourage exploration?

Very cool. Short and sweet design. Solid theme/atmosphere.

Lovely architecture, interesting fights, enjoyed it all. Short and sweet.

Unpopular opinion: brushwork aside, this is not the world's most remarkable map.

Love otps new self.

Fun map. Doesn't take long to play through. 10 minutes or so. If only there were a few secrets! Definitely worth playing.

This is a solid small map. I really appreciated and enjoyed the vertical structure and how quickly you unlock access to the next area, it was sort of like reading a short story with a lot of chapters.

The texturing was on point as is the brushwork. I didn't know it was a 100 brush contest entry until I came here to write this review which shows the map is well crafted.

My only gripes are the lack of secrets and the fact I got a bit confused on where to go after unlocking level 5 access. My getting lost may have been due to the fact that I had to save and quit right after flipping the switch and pick up the session later but I feel like it could have been signposted a bit better on that top floor.

If you've got ~5 minutes to spare playing through Biotoxin is one of the better ways to spend that time.
