Not sure why, but when I click on the "Web" link - it just leads me to a blank white page.

One possible bug: I saw a ball get stuck as if there were an invisible ball. Also, the music did not seem to restart when I lost and played again.

Creative puzzle idea. It gets complicated when things affect balls to the sides as well as balls above. It might be nice to add some sort of target indicator so you can tell exactly where the ball will go.

Does the monster do something? I did not notice it having any effect on the game.

Emphasis on the hard to master :P

This is a very cool game, with a theme tacked on just as a show of good faith to the Dare.

Really simple and fresh puzzle mechanic! This didn't work in Safari for whatever reason, but I was able to play in Chrome.

Fun!

Great graphics and a neat mechanic... it'll take me some time to master it!

Very neat. I also saw the bug GAFBlizzard says, but quite polished apart from this. Nice music too!

I got addicted, fun concept and the music feels very genesis like.

Yeah, unfortunately it's a bit buggy when you try to shoot a ball as a new row is added :\

I couldn't fix this in time before the 6pm deadline today, but I do plan to continue working on this and polish it!

For those interested in the technical side of things, this was written completely in Javascript and the engine I ended up writing from scratch during the Ludum Dare is here: https://github.com/kcaze/Monsters-Reversed/blob/master/js/engine.js

The technical details of the bug is also quite interesting, because it essentially boils down to a race condition, which technically cannot happen since Javascript is single-threaded, but you can have bugs that are similar to race conditions in nature.

Awesome puzzle game. Really fun, occasional bug (ball stuck on invisible wall). And it seems like only one line can clear at a time? Anyways, really fun puzzle game!

Very nice. Simple and solid.
But sometimes when I fill the whole horizontal line - it does not disappear

Okay, all the bugs should be fixed now!

It's a fun and well-designed game but...it's not really part of the theme. The theme could be anything in this case tacked on and it would still be the same game.

It's really hard for me to rate because the game is well done but the theme just isn't there.

That was really difficult. Doesn't help that I suck at reversi. xD Neat idea, though. I like it.

I'm not good at reversi so this was pretty hard for me. I could kind of figure out when it would change color but not always. Maybe if it started off at just always switch the one it hit, and then different monsters could have more complicated kinds of switching for a kind of ramp up.

You're awesome because you made whatever you wanted and stuck an image of a monster on it instead of whining about the theme and dropping out.

It's a very nice match game! Casual game are rarely seen with this theme.

Nice puzzle game which does take getting some used to but once you figure it out it becomes quite a fun game. Would have been nice to see the monsters tail looping into the game segment and shooting out it's random coloured segments which would keep expanding.
