Maybe it’s too short, but I’m really surprised that you made it in two days. BUT! As someone said already, controls are feeling really good, but too bad there is no way to use arrows instead, or use space for dashing. That’s the only reason why controls were not perfect for me. Also I had some rendering issues (vertical lines between tiles), but that’s not that critical tho. About soundtrack: it’s just awesome, can’t really say more about it. I’m literally writing that comment while standing in the middle of boss fight room. Too bad there is no title screen, because soundtrack in here is really awesome too c:

About downsides thought, there is not that much. As I said already, it’s kinda difficult to control with keys being too close to each other, adding support for arrow keys or alternate dashing may help. Also hitbox of bubble is a little weird, maze took me a while to get through. There is also small hole in the first room of boss area (5th tile on right side), but it’s fine

Overall, 9/10 for that short development time. Good job, exi & fxg. Hope there will be at least something in future! 73
