I can definitely see the Binding of Isaac influence here. The one-resource system makes it easy to manage what with the coins and everything. It also keeps people interested in the coins regardless of their strategy, whether they prefer using coins for jumping or fighting. The powerups are few, simple, but powerful, making it very easy to keep track of what does what, a pitfall that annoyed me a lot when playing Binding of Isaac (you needed a Wiki of all of the items, honestly). The random item in the shop seemed a little gimmicky to me, since the game itself is so short.
Anyway this is a really great roguelike. Nice and short, much more casual than others. Like all roguelikes there are a shitton of cheap deaths, and that took away from the experience for me. The graphics could have also used a boost and maybe some different music as well.
Also, I think something could be done to make the final boss a little more fair. I've lost to it maybe eight times now, half of them due to grunt enemies. It's also way too easy to fall into him. Instant death is far too harsh of a penalty. No other game expects a player to cope with that kind of insanity.
