I reached the fox once so far.
The game looks pretty cool.
It is super fun, the speed of the bullets seems right and the game is challenging, I like that, it's bigger that I thought when struggling to be able to cross the bridge a first time, and uncovering a second boss was a pleasant surprise.
The lack of feedback (and possibly invulnerability frames) when you get hit is a bit weird and I wonder if the hitbox of the rock is not just a little bit too big but these are very minor details.
Very cool game, thanks for sharing.
