What a bizarre movement system. I feel like it can be mastered, but it's beyond me for now.
I love the idea of every upgrade also buffing the enemies in some way, so you get to pick your poison. You can sometimes get the same combination of upgrades and downsides on both choices. Maybe you can re-roll the options if that happens in a future update.
There's not a lot here right now. No music or sound, only a couple of upgrade options and one enemy type. Maybe I'll update this if more is added.
