Good game! I liked the pace of of it and the music was good, as well as the art!
The mechanics where nicely unique. A lot like mario but with some different features which i liked.
I did find a few glitches and things i think could maybe have been improved. The hearts for your lives could have been a little smaller. When I first started playing i didnt realise i was being killed and just though i was randomly respawning.
Another thing is that when i fell and didnt grapple, i didnt die and was able to run along the floor, oof screen and under the map.
But overall a very good submission!
