Well...
This game has a lot of potential to be fun, however the main problem is that it's just far too luck reliant. It's extremely disheartening when you don't save up for a gold ticket, about 3 stores within 20 events pop up, yet when you actively try and save, you get 1 in 30 or 40. The fact that you have to have a gold ticket in order to get any meaningful progress in the game, let alone 100%.
There's also the fact that Dragons completely obliterate you unless you've upgraded a lot or have one of those divine blades. Also, the fact that you don't need those blades except for Dragons makes it extremely nerve racking when you see one. It basically forces you to gamble on either a game over or wasting 200 gold.
You can easily fix both of these problems in that game you're going to be making by basically giving us markers for when the Gold Ticket houses are going to pop up. And by that, I mean putting a number that tells you the number of events that will transpire before you reach a ticket.
For the dragon a simple Divine Blades right in front of a monster is really all you need to signify that, since dragon slaying is pretty much the only thing you need. I really wouldn't be stressing this if the elixirs you can get are much more reliable than a single instant kill that only buys time until you can either buy an elixir again or an armor upgrade.
But overall, the game was pretty fun. I enjoyed the simplicity of it; it's just that there's a little too much luck involved in my opinion.
