Your pixel art is very solid, and the concept is pretty cool! The only things are I felt it was a little bit on the punishing side, with dying in a single hit in addition to the lightbulb being an alternate lose condition. Additionally, the movement felt a little… Off? I don’t play a ton of platformers, so it’s hard to say why exactly (plus I’m not used to using the arrow keys) but I’d say it’s a combination of particularly harsh gravity and a lack of coyote time that makes it particularly difficult. Also, being able to hold the fire button instead of spamming it would’ve been nice, but needing to spam it gives the game a more frantic feel, which might’ve been the idea.
