I like the concept, i liked the 3 other one but...
This one is by far the worse.
Why?Because, unlike the 3 other, it doesn't depend of your skill to win, but only to LUCK.
Why?BECAUSE THE 4 CANONS SHOOT RANDOMLY
Thats the prob with this one.You can evade easily the 2 balls, but you need to cross the middle 8 or 10 times before they disappear.And most of time, you wait than the canon shoot to go just after.But sometimes it don't shoot, you're forced to cross and die because it shoot right at the moment you crossed.
So, 3 things should have improved this game:
-Add something to show when the canon will shoot.A cooldown, something, but which allow you to know when you can cross.
-Or, just remove the randomness of the shoots.And make each canon shoot in a timable moment
-At last, your "slow speed" is useless.Even at the end (when the two horizontal line narrow themselves. It's slower than the walls.Then, you should speed it a little, or, at least, allow us to use the keyboard to switch !It's really awkward to use mouse with your left hand, and if you need to switch fast (like at this moment) you can easily slip :S.
I don't think you're lasy, just because i can't do the same, and it's really addicting.But you shouldn't create game based on luck like on skills, like this one.
