Would be nice if I could resize the game. Going into cinematic mode just leaves a large white space since the dimensions of the game are hard coded and it doesn't scale. I run at 1680x1050 resolution so the game itself is just a tiny, tiny window on my screen and it's very hard to see what's going on. I get that this game is 4 years old, but come on. I know people weren't still using 600x800 in 2009 either...
Terrible collision detection doesn't necessarily make a "hard" game a good game. You could have just made the player square invisible and called it a "hard" game but it would be awful. Fix the collision detection =/
Found numerous other bugs since my last comment. When you get game over and then click Reply or go to the main menu and then select play, the game doesn't actually reset block drop speed. I'm at "Level 1" with only the 3 starting colors but the blocks fall NON STOP. I made it to level 2 and it's impossible to click fast enough to win. I actually had to close the browser window and open it back up in order for it to actually reset to the real level 1. Also, sometimes you'll lose without the 10 second countdown. More major flaws.
This could be a great game if it weren't for these very major problems.
It feels really unresponsive. Sometimes I have to click 2 or 3 times before it registers. Not only that, but colors that ARE touching don't register right away. It takes a few seconds and sometimes you have to mouse off and then back onto a color in order for it to register all the adjacent blocks of that color. Both of these issues are pretty major flaws in my eyes bringing this down to a 3/5 for me.
Great game, it's just too bad it took 22 levels to get challenging. The last level only took me all of about 2 minutes to complete. Definitely needs a level pack and a level editor. Would have gotten a 5/5 from me if it were more challenging and / or longer. 4/5
