7/10

I like the concept, but it lacks some game elements.

Things for this game to be improved:
1. Double Jump
2. Shift for Boost/Sprint 
3. UI/UX
4. Probably a stage/level game (E.g. Stage 6, Level 9)?
5. If it's a continuous level, have some sort of meter for how long is the character from the finish
6. Add at least 2 more music
7. Put the tutorial/control board at the start
8. If it's a continuous game, put like some sort of announcement or pop-up of what part of the map is the character currently in.
9. Add some biome or other elements, so the entire thing is not purely just blocks.

10. Add some SFX. Also when the character reach a checkpoint.

Problems encountered:
1. Some obstacles/hazards has no collision.
2. If I fall out of the map with a block/platform in hand, I spawn with it, so I can't progress further.
3. Controls sometimes are unresponsive.
