Thanks for the bug reports. Can't believe I never caught that. The reason was that I put the boundaries in before I had made the building. The cars are giant because I didn't make them and that's the resolution they came in. If I scaled them they would have lost their pixel appearance and recognizability.
Great art, great music, and fun game. One tweak I would make is ensure that the lowest platform is never out of view by moving the camera, so you can always see where you are jumping. Also, I disagree with adding upgrades since this isn't really an achievement game, it's more of an endless high score game, so upgrades would just negate the need for skill to get a good score. With that being said you should implement high scores with the Kong API since it's on this site.
Fun. It is sort of slow at first and easy until you're forced to move during the round. I like the voicing and the art. I think the binary success of it makes it a little frustrating (you either win or lose). Maybe an option with multiple lives would be fun. And the pace could be faster, or at least adjustable like kjojo said. But awesome work for 72 hrs, and I sort of know what that's like since I made a game for the game in ten days competition here. Hope to see more!
Amazing game, the only thing bad I could say about it is that it needs a game over screen. Otherwise I love the difficulty adjustment and the way the action picks up. The particle effects really make the simple graphics nice too. Most importantly, it's tons of fun.
I think that having the shapes fall down slower but spawn faster would be a good idea, since that way you could see what is coming sooner and strategise. Right now it's just guesswork with what will come next, since there are only a few shapes on the screen at a time. Also, try making the goal and rules a little more obvious right from the start. The graphics need some work too. This is definitely a good idea though, keep working on it!
