Way too laggy. Low quality should disable animations. Unplayable on low-end computers. 1/5 but I'd give it at least a 4/5 if it ran on my old computers.
Game logic has been thoroughly tested and is ok. What might happen, if a word is just about to disappear on the right side, is that you click on the square too late, and thus attempt to erase the next one, losing 2 lives in the process. This is actually a feature.
Going through my or the betatester's logs, every time we thought we were right and the game at fault we discovered that it was our own logic that was wrong.
Well, all this is for levels 1-9, but since thereafter and till the end of the game no further rules are appearing (only the speed changes for levels 8 to 12) , it's a safe bet to assume the game logic stays what it is.
Burnacid: it works as intended, at least for me and several friends/other people on several different hardware/software. Do not forget that you have to act differently on underlined words: with them you must click the color they're written in, not the color they're spelling.
Example: on the bottom screen, a blue "Green" word should be eliminated by clicking on the green square, but an underlined blue "Green" word should be eliminated by clicking on the blue square. Rules change further later in levels (Read the rules carefully...)
Rombest: does it happen when it has almost disappeared? It's often a bad idea (pun not intended) to attempt to destroy a word that is almost out, as you might be a few milliseconds late and erase the next one. Call it a strategic choice: leave it go or risk losing two. If it's something else, well, I'll look into it
