Pretty lovely and polished game, in fact, it doesn't feel like a Jam game at all, it feels like an regular length game.
it's truly amazing the amount of content that could be put into the game in such a relatively short amount of time.
The gameplay is a little repetitive and the enemies are more annoying than challenging, but those are just my opinions and it could just be part of Metroidvanias as a whole.

There are a couple of bugs as usual with any jam, Screen has a weird glitch effect

The crouch button isn't the actual crouch button, it's Down arrow.
Bullets seem to gain trails a bit into the game.

But the majority of my criticisms come (somewhat subjectively) from the actual gameplay, I already mentioned how annoying enemies are; not exactly providing a challenge as they are very much just in your way.
This is also reinforced by enemies respawning immediately, this also feels like a Metroidvania thing, but I don't see why everything would have to be strict especially when it gets in the way of 'le fun'.
There's also HP, which is way too easy to gain, you don't really feel pressed when you lose HP as much as you're just hoping you get some HP soon so you don't have to go all the way back here.

Another major Metroidvania-ish thing, is that I, frankly, am always real damn confused on where to go, so much that I'm genuinely stuck around here:

Probably me being a brainlet and forgive me if so, but I genuinely don't know where to go after the Jetpack.

Game rating: 4.5/5
Jam Game rating: 4.8/5

Best of luck, cheers!
