I've planned a few new features and I want to improve some old features.
- better AI, with pathfinding...
- it takes more than one hit to kill the enemy
- improved HUD
- some improved graphics
- WASD, Space controls (instead of arrowkeys)
- different enemies
- a menu, intro etc.
- a few new areas/worlds
- different weapons
- Armor, maybe a protection shield
- new animations (when you jump, etc.)
