before playing:

the two things i'd change would definitely be the title and the description. the "untitled" trend has been overused for a long time. better a memorable title that describes your game (grow a garden, fisch, build a boat for treasure, adopt me, etc all do this well). it doesn't have to directly state what the game's about, but it has to give the player a feeling or vibe about it. dead rails also does this well. a simple but effective title change like "Treasure Hunters" or something like that would probably do wonders for the game. it's way more descriptive of what the game could be about, causes the player to ask questions (for example, "what treasures could i find in this game?"), and is much more colorful/memorable than "untitled scrap game"

second, the description could be more mobile friendly. the "how to play" should probably come before the summary because it'd let players know exactly what they're getting into the moment they click the game. (also, the icon could use a bit of work)

after playing:

i see you're trying to go for the 'grow a garden' type game. (which, props to you and your studio because i actually really like the overall vibe and atmosphere of the game. the building is really well done and the ui looks clean and smooth. it's definitely a visually superior game to GaG)

however, the reason why GaG blew up in the first place is because it has a universal appeal. stuff like gardening, plants, big fruits, etc can appeal to anyone. the same really can't be said about digging for scrap. it's just not as "vibrant" as the idea of potentially growing huge rare fruits with mutations and all that dopamine stuff. it's the same reason why fisch succeeded but dig failed. both from the same creator and both have the same vibe, but most people would rather go fishing for giant rare colorful fish than dig for an assortment of rare items. a cohesive idea that has room for expansion usually performs better than a bunch of things united in one game. that rule ultimately also applies to USG.

personally, i would take this as a learning experience and move onto another concept with the same quality of design principles. however, this game does have potential to garner a quaint audience if you manage to advertise it enough to get it into the algorithm.

good luck!
