Very nice entry! I liked the concept a lot and I wished it had more content, which is great, being left wanting more is awlays a good sign for a game I think! I know time is scarce and I understand cutting content very well though. I liked the little map, but as it is I didn't figure out if there were any differences between different nodes. I went for an imprecise machine gun build (I just love attack speed so much in these games) and cleared the game first try.
Minor things I didn't like (while still enjoying the overall game very much, let me be clear):
- I think enemy bullets should have better contrast for visual clarity, either through different color, or an outline or both
- I felt like everything moved a tad bit too fast (character/camera and enemies), but this might just be personal taste or old age
Congrats and thanks for creating this nice little game! Keep up the good work!
