Have to agree with the below. More balancing for the lower number of players is needed. Lower world boss HP (or strengthen attacks) to make them killable and possibly lowering energy refill time to make up for lack of PvP to make gaining levels easier.
Easy game once you get a hang of it ...
Level 1: 45 degree angle, full power. Level 2: Floats ... 45 full angle then use floats. Level 3: 1 thrust, 1 float. Use thrust then float. Level 4: 2 thrust, 2 floats. Level 5: 3 floats, 3 thrusts and upgrade. Level 6: 3 floats, 3 thrust, 3 freaky's and rest on upgrade / powder. Last Level: All upgrades.
Always use thrust as soon as you leave cannon then use floats and last freaky's. My best score: 7600

Thanks for the comment! Ways to balance the game for a smaller player base are always something we're looking at, and we appreciate the suggestion.
