Hello. My achivement is not showing on my profile after doing what it says.

?

Has anyone ever notice this or is it just me? If you are in a level where an extra life exists, you collect it and died in that level, you can still collect it again after respawning. I don't know if this is supposed to be a mechanic or a potential bug/exploit. But given that the game can be challenging, it is hard to tell....

Something that would be very good for the game is that it had achievements. For example, it would be good if there were 2 achievements of beating the first chapter in easy and hard.

ist the release date?
