Good game! I like the character and environmental art here. I also like the unique take on double-jumping, although it didn't always reset my jump properly. It also could have been clearer what all of the pickups do. I believe only the first ability had a help message indicating that the player powered up. The final boss had some cool attack patterns which required the abilities to overcome, but the boss could use some more balancing. I ended up cheesing the boss by standing in the corner and slashing it. Overall, this is a solid game!
