Ah, the spirit of Donkey Kong lives!!! I loved double-jumping over the obstacles. That felt so satisfying.
The first several rounds were very hard, but I persevered until I managed to beat it.
Note that the game crashed on me a few times, mostly after I got hit (but this didn't happen every time I got hit).
The primary gameplay loop is solid, but the game could have benefited from more levels, as well as collectibles or other secondary goals.
