Hi NovaGames — the map-vote screen looks like a useful place to start, since your voting logic already works. For four players, I'd make the chosen map, vote counts and countdown readable at a glance, with a clear selected state that doesn't rely only on colour.
If a fixed fee fits your budget, I can offer US$25 for that complete UI asset set: one layout for up to four map choices, vote/countdown labels, default/hover/selected states, editable SVG and transparent PNG exports, plus one revision round. This covers the visual assets; your existing GDevelop voting logic stays with you. Delivery would be within three business days after agreeing the brief and receiving your current screen dimensions and map thumbnails.
Would that paid scope work for you? A screenshot of your current vote screen and one visual reference would let us agree the style before starting. We can quote the menu/HUD separately if you like the result.
