Incredible performance to have completed a game with so much feature in just one month, this is very qualitative work !
I don’t have anything bad to say about this game, everything is super well done here : complete inventory system, very well interesting level generation, lovely graphics with a good color palette and lighting, and a good UI.
Congratulations on this awesome game ! I see in the inspector that the UI is in HTML, so I imagine that the game itself is in Javascript, will you perhaps make the source public ? I would be super interested to read it.
