I never in a million years thought I would like this game. Then I played it and found it to be a truly wonderful flood of happy brain juices. Glad to see it still putting out strong updates
When it first started, there really wasn't that much to it. One "map", a couple characters, a handful of weapons/items some of which had interactions. Barely even a video game.
Since then, there's been systems added and fleshed out, more characters, more maps, more modes, more everything. Now it's a fucking video game.
I thought the same thing, but now I've probably got over a hundred hours into this game. It has great progression, with tons of fun unlocks and different types of levels. For under $10, it's a great deal.
