I love the approach to the theme, but I must confess that the music and the theme give me completely different vibes. The game suggests high adrenaline and playful old-school winter shenanigans, while the music takes me to an abandoned hospital that might not be so abandoned after all.
It is a great idea, but I can’t help to feel like some pieces don’t match with each other very well. The walls come out of nowhere to the point that often feels unfair, even for the easy difficulty settings.
The freezing/death bar mechanic makes sense in some circumstances, like being hit by an icicle and maybe moving fast through cold air, but it doesn’t feel very fun. Maybe would work better if there won’t be any other health bar but the avalanche itself, chasing you until it catches you, while the other mechanics give you a different kind of trade-off, like gaining too much momentum and landing on a floor (as opposed to a wall) results in broken bones and a slowness debuff on lateral movement, while icicles make you falling slightly slower for a longer while.
