Beat my score!
It was really fun once I got the hang of it. I love those types of games, bonus points if there is a rythm in which you have to hit the combinations.
Everything I would critique has already been said by jazhikho, so there is not much to add.
In our last jam, a few weeks ago we actually made a similar game. There you had to move and jump using WASD and hit arrow key combinations to do stunts while being mid-air. There I added sound effects that increased in pitch for every combination you correctly hit. I think something similar would have greatly improved enjoyment of hitting combos in your game too. ^^
Good job on your entry!
