this is the first game i've played from the jam so far and my immediate impression was that it just jumps straight into the game without warning, and it took me a second to figure out what i was meant to be doing.
the jump and double jump have a really snappy and polished feel to them, and i really liked the colourful spritework for the cityscape in the back. i couldn't figure out how to use the charge (dash) or switch gravity though until i checked the page, the gravity does feel similarly sharp and cool but i didn't understand why i needed it? and the dash felt less smooth compared to the other movements.
after a few seconds in i was unsure if there was something i was meant to be looking forward to, didn't understand what the point of the lives were (they just went to the negatives?) and didn't get a sense of progression. i only got up to one colour change of the scenery which looked pretty but i didn't get why i got there and if anything else was actually changing at all.
the link to the theme also feels a bit weak, nothing about the mechanics or visuals really lean into cycling very much, was it meant to be ironmouse pink? i'm sure you're already aware of these flaws though, and the movement did feel nice and fun. good luck on the next patch.
