The game lacks some feedback and explanations. It wasn't obvious to me what I could interact with. You could write on your itch page with what you can interact and what it does. It would help newcomers a lot.
I had a hardtime with the dash to cross the first obstacle. I had to release every input except for the '1' key while looking at the right direction. I am not sure if I used it correctly. Making it work while also having a movement key pressed would make it way more intuitive.
It's hard to make the enemies do what you want. I had a clear plan in my mind, but my plan would almost always fail and I had to rely on luck instead.
You could easily add some more juice to the game with some sound effects (on interactable, canons and enemies).
I did not complete the whole game, I stopped at the level where there are a lot of enemies and two cannons (one on each side). I tried multiple times to make the enemy follow me, but I always died to their attack in the doorway. I also tried to use 2 bombs to kill them all, but I did not manage to stack them enough.
Congratulations on making a game ! I had fun trying it :)
