This is a great game overal, good concept, a good level design that knows how to play with the main concept(jumping kill's you), and an very original implementation of what a metroidvania can be.
What I think could be better:
- Some kind of feedback when lossing hearth, I died a lot of times because I forgot about my hearth.
- Animations, Sounds and Presentation in general, But this is very dificult to have in time for a Jam.
- When I land on the diferent colors and effect is applied to the player(lossing or gainning hearth), but this doesn't happen when walking over, this limitation makes the games harder, but is agains what normally happen in most games(effects on collition) so is not very intuitive.I didn't get how that works until late in the game, so maybe a mini tutorial explaining that could help
