This was a fun concept with good music (although a few sound effects were too loud imo). I think a lot of good mechanics were available for use, but it was sometimes unclear how some mechanics like boxes were supposed to be utilized strategically, and some things were unbalanced in the player's favor (stamina seemed infinite, usually enough bombs to take out all enemies pretty easily). My personal opinion would be taking out one or two of the side mechanics and focusing on refining a few of the mechanics you want to be the "core" that enhance the gameplay loop the most. I think you've got the start of something really fun here, thanks for the experience!
