I think some look-ahead towards the cursor would be nice for when you’re moving very quickly, but otherwise this was a fun little game. I never ended up using the bombs and just maxed out my speed lol.
If you wanted to add some spice to the game, I suggest changing the zooming the camera out and easing back in quickly whenever you pick things up, especially the keys. It adds a little punch to the movement. I wouldn’t make it really strong though, because it might mess up the aiming of your movement. Adding a light screen flash would also add to this but that might be too much for this kind of game.
Good work! :)
