I do appreciate the feedback! I actually just found the stream vod from your discord link so I got to watch you type this after the fact. :) And yes, it was my first game jam and first completed game.
Your criticisms are totally fair and I too wish the level design was tighter. I spent most of the jam building out the systems - a number of aspects like making the UI were completely new to me, and I had essentially no code reuse from my other (unfinished) projects. So I ended up with about a day and a half to make all the levels, which meant I had little time for testing and iterating on them. I am glad I did the jam as it was great at getting me to actually finish a smaller project, but it was very stressful and I would love to actually have time to do playtesting with whatever I work on next. :)
