I've played through it about 2-3 times. It's okay enough for $4, but I wouldn't call it a steal. It's only 9 chapters, it's fairly bug ridden, the balance is wonky, and the AI can be slow and tedious. There also have not been any game updates since I bought it about a month ago.
Overall, the game is a nice novelty, but I can't recommend it without any news on (much needed) updates.
EDIT: Creator was on break and is fixing issues again.
