The punishment for clicking the wrong thing is too long. Just write the message and zoom out. You don't need to do it so slowly, and you don't need to zoom out in two steps.
Sometimes the game gets into a state where it stops accepting input and the character just goes off in whatever direction it was going. Sometimes jumps just cut off shorter than they should have.
The game tends to get into a weird state where hovering over your planes turns the cursor into a hand, and the game doesn't give you any information about your planes, such as how much life you have left. I'm not sure but I think it only happens after you've taken damage.
@tlemm3, first place a duck in the middle, then the opposite corner, and then a second corner to block. It doesn't always work. If it doesn't work you just have to do it again until it does.
y2k_bug, I noticed that too when I first started playing. It doesn't affect pros at all, but it really messes things up for beginners. No warning or anything, it just has a secret max time limit of 1 hour.
Requiring a mouse for the menus was a poor choice. The game itself is keyboard only, so the menus should be controllable by the keyboard. It's too annoying to switch just for the menus, when they could have easily been controlled by the keyboard as well.
Instead of advertising your other games every single day, try just making a game of your average quality, and then people will know whether or not they'll like all of your other games. Your advertisements with forced minimum view times makes the game less fun, and less likely someone will want to try your other games.
"Don't Click! Just hold it down!" You know that you have to click the button before you can hold it down, right? It would be clearer if you said, "Press and hold the mouse button." Although it would be nice if you just had to click the mouse button instead of holding it.
