Really cool game, always love to see a momentum based roguelike. It was really fun zooming around the map, occasionally making huge mistakes and slamming into things. At first I was unsure about the lack of enemy variety, but I think as they are they serve well as a tool to force the player to keep up the speed.
Loved the different map generation elements as well, the holes in the floor were a cool obstacle, and the more tunnel like areas were a nice challenge. When I got to the internal areas though, that challenge began to tip over into frustration, as they were just a little too cramped to really let me do what I wanted (which was go fast). Didn't end up beating the game because of this, unfortunately.
There were some pretty straight forward polish items that might be worth addressing as well.
- The restart button has no confirmation, I hit it accidentally once while trying to brake.
- When going really fast it makes sense to play from zoomed out, however enemies and items do not scale well with zoom, and are hard to see. Symbols to represent both at higher zoom levels would be nice.
Overall really cool entry though, as I said earlier, momentum roguelikes are a big favourite of mine.
