thanks for the detailed feedback. I'm glad you like it. As for your suggestions:
- I've tried making the starting speed faster, but it will lead to the speed getting REALLY fast after the player upgrades several times, so I have to make it slower so the player will have a motivation to upgrade the speed.
- The health bar (green bar at the top left) already decreases by 1 point every second, I am hoping this will motivate the player to move around, collect the cyan triangles, and get upgrade for health. But your 3 hits health idea was also good, I wonder why I didn't think of it when I made the game.
- the character's face was originally just blue, but I didn't think that would make a good character, so I tried to make it more interesting. I didn't know how to make the face better while keeping to the theme of the game jam, so it's the best I could do. Thanks for the color palette link, I didn't know about it.
- yeah, getting hit by a near transparent triangle is really frustrating, but if the triangles just disappear all of a sudden, the game would feel weird IMO.
