Some other remarks and questionsI found:
- Already mentioned below, key bindings please! It's probably me, but I'm constantly mixing up (or pressing together) dash and fireball, causing a lot of unnecessary damage
- What's up with the bones? Is that 'just' your score? Or will there be other uses?
- In the far right box in the purple zone there's a gap in the map, even though you've been right near that wall
Aaand, finished it! Nice experience, really good basis to build on!
