I don't understand how sloped blocks are a bad thing??? It's not as if theyhave to slide you around. Just smoother so you don't need to hold spacebar all the time.
Also, and we've all suggested this, BACKGROUNDS. Also online multiplayer, but I understand the second one will be hard to program. The first one is easy tho, just don't give blocks collision detection :l
I was thinking, what if you had spent energy on something you didn't mean to? It would be worth anyone's time to implement a button that takes your energy OUT of a certain pack. That, and the thing with the crew extras menu not appearing 5/10 times.
What's with the bird smiley? It's really obscure in the way that some people have it but you can't get it anymore. I get that it's in a contest, but at least leave it in the game, because I really wanted that but I missed the contest. How can I get it now???
Try using a different character. They all have strengths and weaknesses, so maybe this just isn't a good level for the Lizard.
