Congrats on completing your first game!
Viewing post in Mlood - My first game ever (sort of) jam comments
Well, just for presentation stuff, I might suggest communicating more outside the game - stuff like posting the controls on the game page - I like to know how to play before I start something up.
The ‘how to play’ screen in game is fine, you did good there.
Also your web build doesn’t work if not full screened and there may be other issues - just a bit of text to let people know the state there would be helpful.
