The Passage

It's fun to play and it s hard to master :D well done! 
I would add: 

-A score: It would help me to keep track of what i'm doing

-"Damage boosting":it means that if you get hit, you get some kind of invincibility for a sec. That would help me (the player) to feel less defenseless when I get cornered with spikes .

-Upgrades: It would be cool to "buy" upgrades for the player to choose, more damage, more speed, bullet types, more "damage boosting" time, etc... It would add a level of complexity and it would be more engaging for the player to see things that can be earned to ease the game.

You have a good game here. Thanks for making it! ;)

That's an original game. I have never seen anything similar! The fact that shooting at the bombs makes you fall back makes it a really interesting challenge.

I made it to the black bombs, while playing on a mouse pad, so proud of myself :).

There is a small inconsistency in the graphics: The player is a hand-drawn character with a fat black boundary, but the bombs look perfect and only have a small boundary.

So, it's okay.  I like the concept.  One thing that I would recommend though... progress number.  Just something to indicate how far you got.  I think that would have a significant positive impact on the player.

Although, really, you probably already knew this and just didn't find the time in the jam.  I know I cut important stuff as the end closed in.  But yeah, fun little game.  Good work.
