This game currently feels really odd, which is understandable considering how early in development it is.
The main thing that confused me was the very sudden ending with a black screen telling me that I failed to survive for thirty minutes even though I was at full on everything and thought I was doing pretty well.
Maybe a bit more of a text based tutorial that explains the world and such as well as an endless mode since having the game on a set time limit really makes it difficult to fully get a grip on what you're doing in the first playthrough before the game abruptly ends.
It definitely seems to have promise though, especially the card game portion, although it's currently a bit difficult at first since you essentially have to win twice in order to win once and your own cards tend to "damage" you more than they do your opponent.
Definitely keeping my eye on this though, because it does seem to have a good ground for a really fun open world game.
