Looks like you had a lot of graphics to make for that game because the shop has a lot of details. So good job with the arts!
I played it till the end (22days) and found some bugs:
- Once I reached the end it says it took me 0 days
- Upgrading to lvl 5 (max-lvl) is for free. So if you have 50 coins and everything on lvl 4 then you could buy all upgrades ... and you still will have 50 coins left
- Some chests don't tell me the price. They say in any case I wouldn't have enough money
I like the actual game idea. It is a mini version of ShopeKeep and really turned out really nice. But it first become fun in the "late game". I'd say you first notice the limitation once you've upgraded your shelfs to at least 3 (depending on your speed level). This was then also the point where the game started being fun - because I really had to plan my routes and it was benefital if I end my day in front of the chest. Once everything is upgraded the game is getting somehow grindy.
The early stage is mostly waiting. A button to end the current day would be pretty nice. I guess not everyone is as patient as me and you could loose players.
So overall I really like the game and the idea behind.
