Great platformer and nice retro visuals. The checkpoints felt extremely satisfying to reach!
The first two sections were probably my favorite in terms of game design. I love how you add new mechanics but took away some freedom of movement that you had previously. I think it would be really cool if the later parts also do that:
- Legs don't let you jump as high but you have regular walking movement.
- The gun auto fires and each time it fires you have recoil so you're forced to either counteract the recoil or use it to your advantage.
One piece of polish feedback is that it would be nice to have some sort of screen transition for when you die and restart from a checkpoint. Right now objects just despawn and respawn and it feels a bit jarring.
