Don't be discouraged from a low score on this version of the game - it's an ambitious project.
Unfortunately, I had a few problems.
- the character can jump in midair by pressing space as you fall from a block. Not sure if this is intentional
- After the hill to the right I fell out of the map
- jumping up the hill itself was glitchy as the white line on my character sent me downwards quickly
Nice start, looking forward to seeing what comes out of it.
