I appreciate the generosity of the checkpoints. The platforming felt a bit stiff at times, so the checkpoints did help reduce any frustration caused by that. The snowstorm section especially amplified the limitations of the controls.
I'm not sure if its a web exclusive issue, but there is an unfortunate bug with the jumping sound effect. It sounds like the game is playing the sound several times in a row at once. Resulting in a sound that isn't the greatest on the ears.
Earning new abilities along the way is a neat concept. There is certainly potential for that to enhance the level design if explored further.
Wishing you the best on any further endeavors.
