For a game done in a week, this is pretty solid!
The graphics and music were great! Even if a little bit light on sound effects.
The dying temporarily mechanic was pretty unique and fun to use!
Main issue lies in the controls. It was interesting to see the traditional WASD format ditched with A to run, D to use your current "special" thing (idk the name of it) and S to attack, however while D felt pretty natural, A and S felt a bit weird.
I got stuck on the first boss because I couldn't really get the hang of jumping and grappling at the same time. It felt weird at first but on a second playthrough it didn't feel as bad, however I didn't have time to progress back to the original boss.
Even with these negative points, the mechanics were creative, the graphics were awesome, the music was cool, solid entry!
