It's small and simple, but good fun and absolutely worth the price.
Charming visuals and tool animations, plenty of encouragement to try a variety of builds/strategies, the simple satisfaction of accumulating a bunch of stuff or building an aesthetically-pleasing farm layout.
The biggest issues are extremely rough translation, wonky game balance, and good old-fashioned bugs.
Overall balance is the most egregious. Focusing on certain activities/products can really make or break your experience. For example, you might go for a certain refined end-product that requires a bunch of buildings, resource farming and daily click-intensive processing to create, versus another strategy that makes you a lot more money for basically clicking in one spot each day. Other systems have similar issues; the daily and weekly passive buffs/debuffs and Monday/Black Market perk upgrades showcase a balance philosophy that's just kind of weird in a way that's hard to articulate. For example, you might pay 5k for a perk that will end up passively netting you 30k per week, vs a 25k perk that actively makes the shop worse.
Still, it's fun and enjoyable enough to 'figure the game out', and by the time you sort out which strategies/perks/builds are powerful vs. garbage, you should have absolutely gotten your money's worth.
