Usability Improvements! - 0.7.0

Yet again time for more updates!

Has been a little since last build, so here's the new additions!

That's about it for additions this build, I'm pretty happy with the progress!
Up next on my list of features is:

• Fix all current weirdness/bugs
• More optimizations ( would love to get everything closer to 50FPS)
• New shape & fill tools
• Tool sub options window (Tool shape, pattern)
• Selection & Copy/Paste?
• An easier way to transfer .PDI files off the Playdate

Thanks for checking out the project so far! Again, if you have any feedback on this new build lmk! I want to make a drawing app everyone can enjoy using.
