Hi! First of all thank you so much for your helpful comments ^^
We're aware that many players find the current controls inconvenient and we plan to include an option to remap them in the full game! In the meanwhile, players can use a controller if that's more comfortable to them.
We're also aware of the sfx/music issues and we plan to fix it on the next version, sorry about that ;-;
As for the comment about lack of context at the beginning, we'll definitely take a look at it :)
Thank you for your support ! :D
