I think you did a great job in pretty much every aspect, the game was fun, the graphics were great and the music was groovy to say the least.
I played both the jam version and the post jam version, you have definitely improved the tutorial and game mechanics between them, and it makes the whole thing easier to understand. However I still find it a bit difficult at times to activate a dash/flip, and sometimes I get damage that feels kind of cheap as a result.
It's an excellent game in any regard, and was improved even more post jam. Fantastic work! Perhaps we might even see this game go beyond the jam?
(To be clear, I did rate the game before playing the post jam, just to be fair)
