A few things:
1. The game crashes or hangs upon trying to enter Options mid-run (Only Options. Configurations works fine.)
2. Quote feels strangely floatier than he should.
3. I'm not a fan of Polar Star and Nemesis being the block maker and destructor respectively. I'd create new weapons to replace them in those roles and give Polar Star and Nemesis their original properties back as a random weapon spawn.
4. Consider giving an option to how high jump is handled ("charge" to high jump, "always" high jump, and "double" jump).
5. Lastly, I feel the first level for basic difficulty is a bit too overwhelming in the number of traps and how often they hide in a leap of faith, and how often high jump is needed to get out of situations.
EDIT:
6. The terrain generation FAILS to consider Polar Star, Nemesis and Charged Jump's status. So if you turned them off, you're likely to be SOL
