I like the Icy Tower vibe to this game - it's plenty hard, too 😁
Technical-wise a keyboard-only option would be nice - I'm playing on a laptop, which made maneuvering the character with mouse extra difficult; it also looks like the game doesn't support resizing its viewport (be it through resizing the window or just going fullscreen), which adds extra difficulty-points on 4k screens (since the game window takes like 1/10th of my physical screen area 😅).
