Updated to v0.7

Hey! It's been a while (again).

The main thing is that I revamped the first three levels (again lol). Thematically, I felt they were a bit too open for a sort of factory setting. Gameplay-wise, I tried to ease the difficulty curve. Level design is quite difficult -_- I also added a fourth level, a checkpoint system, and (moving) sawblade hazards. Sawblades are nice because they still fit the factory setting and can cover wider areas than spikes, because spamming spikes can look weird as if having random spikes and sawblades lying around isn't weird already.

I know I've been inconsistent with updating this. Been on and off due to general life stuff and multiple interests, but I do want to add more to this game. Just keep this game in the back of your mind.
