Thank you for playing! <3
Actually, this can happen. If you use keys in the wrong sequence, or accidentally waste them, you can totally softlock yourself.
Later you'll find Sprints, collect Arcane Resonance, can use Kicks, and also buy Respawn Points to mitigate some of that. As long as you don't reroll the World Seed, the World also stays persistent. So restarting, trying something different, and finding your way around eventually, may be inevitable (it's an old game xD).
The first 2 Regions are procGenerated, afterwards the game picks from a pool of handcrafted Maps, and connects them to a World for you to explore. Full release will also include the Editor, where you can design your own Maps, and thrown 'em into the mix.
I'm going to upload a patch in the next couple days, with some bugfixes, also nerfing the overworld Water-tiles (they won't be deadly anymore), and supporting widescreen.
