It's incredibly addictive, but If I had to say something negative is that success is about 65% dependant on how benevolent the RNG is feeling, no ammount of strategy can do away with 5 S blocks in a row, regardless of how wide the tower is at the start. And I can't apply that same criticism to Tetris since there blocks disappear. But overall I'll strive for the Impossible badge!
I think it's very fun. But big issue in my opinion, it has some collision detection issues, I'm clearly striking multiple enemies but I only hit one. It's annoying when a greatsword feels so weak. Other than that the style and all is very good and I like th progression
Like others have said, the double jump is very finicky. Platform edges seem to be very slippery and even cause some unfair deaths. But overall the concept is fantastic, I even managed to pass some puzzles by some unintentional methods, wich I think should be more pronounced in the potential sequel.
It's visually stunning, I love the artstyle, it's probably the best looking idle game since Cookie Clicker. Besides that it has interface issues, the key/chest ratio is too one sided towards chests. In my opinion it's fun enough for the monsters and setting. Needs work, but overall ot's pretty entertaining as any other idle game
