Very nice game! I liked the take on the theme, and the combat was fun! It felt good, and the particles when your dash was ready again were a nice touch! Graphically it could have used a little more work, particularly the layering of enemies, but I get that it's a short dev time and you do what you can. I do also think the Crashdown text should have been... A tad smaller. As it is, it covers the whole screen and not only does it impact gameplay, I also found myself ignoring it because of it. I think making it smaller and maybe placing it somewhere along the top or the bottom of the screen might be a better option.
Also, I tried playing with the controller first, and I don't know if it's only bugged for me, but... The character moved down when I pushed the stick forward and up when I pushed it towards me.
