wonderful game.. the art & atmosphere are very nice. the items are a great addition and i loved their effects, i love the wager coin in particular. i also very much enjoyed the difficulty scaling.. things like adding another ball or more cups seem like very simple additions but i found they added a lot to the experience. i found it very engaging overall.. i've played it quite a few times over now. it's very enjoyable!
i did wonder though, what's the difference between the void magnifying glass and the devil statue? does one do something that the other doesn't? i was a bit confused by them..
similarly, a couple item's descriptions are a little unclear, but they're easy to find out what they do once you use them, anyhow.
do you have plans to expand upon it perchance? i think it would have a very solid foundation to build upon.. either way, it is a splendid experience and i will likely be playing more (-:
