As others have said, this is a great little metroidvania! I really liked the upgrades you get, it kept me guessing as to how I'd be able to surpass an obstacle later down the line. My only gripe with the game was that the pause between screens can throw you off (especially when you're trying to jump to the top of a screen and jetpack on the next one). Overall, though, this was really fun and different locations were very memorable so I didn't feel like I was lost at any point despite the sprawling nature of the level.
Thanks for making this!
