Controls are solid enough, just it's really quite hard.
The jumps are wonky as. But other than that this is one hell of a good game.
Despite what everone says, I thought the controls were perfect. The layout of the game is very nice. I didn't have any trouble getting all the spheres, (although the hard one halfway through the orange world took some thought.) I missed having music, but that might've been impossible under your constraints.
But there is one bug. If you collect all the spheres in a level then fall to the next world, you are down to 22 spheres next time with no spheres to collect. It didn't stop me from getting the Newgrounds "Perfect Game" medal, but it annoyed me that every time I completed a world, it would say 22/23. I might've even missed a special ending, but I don't feel like playing the whole thing again to find out.
Overall, this no-budget, 48-hour game beats a lot of "professional" games that have been put on the market. Way to go!
I could totally see myself sporting that baggy green shirt and purple cap.
Bug has been fixed. Thanks for the detailed review, glad you liked it!
Controls need work.
A true Nintendo hard game made in under 24 hours. You sir have talent.
