Game, eh?
The game was fun and a bit hard on the side ("Fun and nice, hard on the side") was going to make me give it a tenner. But I saw that the gravity was not of Earth, per se, but that in of the Moon or Mars. So the 'lifelike' physics wasn't really that lifelike. But that got -1, so I give it an 8. I found out that it didn't save, so I was REALLY frustrated!!! However, 'ere are a few suggestions:
1) Make the gravity that of earth.
2) Add a "fire" platform, ie, if you get a green block onto 'em, they turn red and/or burn up to give you negative points?
3) Make the points not out of 100, but what the player already has with a boost of 50 points when he starts the game. The next level, if he has, say, 200 points total, then he'll have to spend THOSE points in the game to pass the level, making it tougher.
4) Add a savegame slot.
Oh, I look forward to the level editor!!!
If possible, could you make a place where users can upload and view other people's creations?? That'll be fun, tho i dont know whether you already thought of that :P
