Really ambitious and impressive for a ten day jam, especially when its your first entry! Im aware that you weren't able to put in a qol features. That being said here are some bugs/problems ive encountered during my play that may or may not be previously acknowledged:
It would be nice to have some visual feedback on when mining stuff, i thought i couldnt mine stone or trees cuz of that. I only realized that i could cuz i randomly decided to give it a shot. A simple shaking of the sprite block being mined would suffice.
There are some areas where i couldnt place my objects. Also there seems to be an invisible collision in the mines
Also didnt know that there was stone pickaxe cuz the recipe book implied that there was only iron pickaxe. Had to use my Minecraft gamer brain to do that. Also there wasnt any recipe for a furnace
When using my pickaxe would be nice to have a durability bar shown, also it would seem that the durability decrease regardless of where i click instead of having it decrease when mining ore/stone
During smelting, the collected items didnt seem to stack properly, i had to drop them individually in order for them to stack.
When exiting the smelting ui the items seem to be flung pretty far from the furnace
Couldnt progress further cuz i couldnt get the purple ore to drop no matter how much i mine it
All of these aside, its insane that you were able to implement a crafting system in such a short time (a bit clunky, but impressive regardless). Hope you can still continue working on this game! Would like to see where this one goes. Also congrats on submitting your first game!
