I like it! The later challenges is tense but not frustating hard while the music and atmosphere felt soothing. The ice character who I'll call Ice with hair and cold emotions is great too. There are a lot of things I want to say:
1. The abilities could be executed at the start of the game for late-game players to have new experiences with the level while having no real impacts on unknowing early players. Or you could just... have it unlock overtime.
2. The gravity felt normal in a jump arc but it felt insanely heavy when falling of a ledge. Applying terminal velocity that limit the falling speed should help.
3. The ground pound could have the ice bounce to make the land felt more impactful. A camera shake would help too.
4. Breaking blocks felt more like opening gates than destroying blocks. The blocks could break apart like how the Ice shatters whenever he dies.
5. If the player ground pound just right and drop to a ledge, Ice will spins like a fidget spinner and bounces off walls like a ping pong ball. And sometimes he would slid at the floor at super fast speed until he hit a wall. It's kinda funny if you ask me.
6. If the player dashes and ground pound at the same time. Ice will not perform the pre-pound spinning and instead freeze frame (nice) with the dash hair before dropping like normal.
But again, great game.
