I could not get on that leaderboard. :D
It's a unique concept for sure. Pretty well polished, simple gameplay. Great jam entry.
Thoughts:
- Hit boxes are too unforgiving. I would clip enemies that didn't even look like they were visually touching me.
- I'm not sure what I would change here, but I kept mixing up what buttons did what. Maybe try directional controls? Pressing upwards relative to your position is flip, forwards is dash, and down is shrink?
- I kept losing track of what abilities I still had and what I didn't. Maybe some color coded dot indicators on the player in the direction of the motion?
- My biggest frustration is when enemies would spawn immediately in front of me with no time to react and it was just an insta death. I'm not sure if you have a spawn range or not, but adding or tweaking it would be welcome.
- Some abilities would trigger in the wrong direction as I approached corners. I'd do a 1-pixel sideways dash when I meant to do an upwards dash. Adding some sort of threshold for the dash that either takes you around a corner or leaps off of it might help.
All in all it's a fun little game that has potential to be even better. I hope you do something with it!
