It was alright...
But there were some things I wanna say about it.
For 1. The platforms need to be darker or in some way more visible, I nearly died countless times for the background and foreground being too similar. Maybe abandon the snow style and go for something easier to see?
For 2. The simple enemies and character seem out of place, try making some actual enemies not just blocks, it will improve the overall quality of the submission in many peoples eyes.
For 3. The music, you need more of it. It started to get on my nerves eventually.
Overall it's a good little platformer and alot of fun but some things just seem to ruin that, the platform colour being my main issue here. Otherwise everything else looks nice or as it should do atleast (coins could do with being revamped graphically too) and some sound and special effects wouldnt go a miss. Otherwise not a bad game, just needs work to become a great game. ~James.
