Never Endin Rock Slide
I just finished my first mini-LD Game ! I could only spend 12h on it (4h+4h+4h) so I tried to keep it simple.
At first I wanted to build some kind of infinite boulderdash runner game ( from bottom to top ) with randomly generated content and water flooding form the bottom of the screen.
The result was not very fun to play, water was easy to block with boulder and always going up was boring ( and not very strategic )
So I finally removed the level generator and changed it to a more classical version with just infinite cycling level as new mechanic.
Few innovations here but I hope somebody will like it 
Only 9 levels to beat.
