Proud to say that I am currently #0 on the leaderboard with a score of 271! I really enjoyed this game, it's super polished and addicting to play. It fits perfectly in the zone of "easy to pick up and play but difficult to master". When I took damage it usually felt like it was my fault and that I could do better the next time. I also quite like the music, and the art style is cute and simplistic but in a good and easy to understand way.
On my first run I thought the only way to dash was by pressing shift which felt really awkward to use. I was going to suggest making left mouse click let you dash so I was pleasantly surprised when I learnt that was in the game all along. It feels so satisfying to dash like that and the movement feels very responsive, but I think making it more obvious that you can do that would be great.
Also I noticed some weird audio popping noises sometimes, especially at the end when it showed your score. Lastly I think it would be great to show not only how much time is left before you can dash, but also make it clear which round number you reached (i lost track of which level i was at because there's no indication of it)
Great game and really fun! I hope this feedback helps!
