I had never heard of this game until 3 hours ago. There was a run in public verification on SDA that got me curious about this game, so I spent my afternoon routing and doing attempts. This is the end result. Note that I intentionally left the cursor visible so you can follow my upgrade route.
This is actually a really fun game. You need to upgrade your speed, jump power, timer, gun power, ammo, etc in order to kill the boss at the end. You're probably supposed to gradually progress as you slowly upgrade your stats, but they made the mistake of putting a lot of easily-accessed coins directly to the left of the starting point. I spend awhile farming those before I proceed. I'll try to summarize my route.
-Upgrade speed, then jump, then speed, then timer. Then upgrade speed three more times (level 5) before farming for coins. This gives us the most efficient rate of collecting this group of 11 coins. I then continuously upgrade the multiplier until I purchase the 100GP multiplier, and then stockpile coins (~330 are needed) before moving on. This will allow us to buy level 6 jump power (required to proceed to the right), level 6 timer (also required to make it far enough to obtain 600XP), and level 7 speed.
-You need 600XP before you can "purchase" the double jump. It seems like XP is awarded by visiting more areas of the map. I can reach 605XP by falling down the pit at ~1:45, riding the platform back up and falling down the shaft at ~2:00. In the process, I also collect the gun which is needed to kill some robots.
-I farm again at the beginning until I have full jump power and 1 ammo upgrade. Full jump power is required to double jump over the left wall, and the ammo is needed to shoot the 2 robots blocking my access to the coins.
-At this point, I farm on these groups of coins until I reach the following powerup levels:
Speed: Level 7
Timer: Level 16
Ammo: Level 4 (8 bullets)
Laser: MAX
This is the minimum level I've found that I can beat the game with. I don't think I can kill the boss with speed 6 and timer 16, but I don't remember. Max power laser gives us a 4-cycle kill on the boss, and level 4 ammo lets me kill the 4 robots before the boss.
-I have not been able to hit the boss any earlier. I've tried double jumping really high (he moves with you) and firing a bullet just before I begin to fall. I have connected with the bullet, but it didn't do any damage.
With some cleaner movement, this can probably drop to 4:45 using this route. I am sure that there is a faster upgrade route, but this is what I came up with in the 3 hrs I spent with this game. Perhaps upgrading the multiplier more would be worthwhile, but I'm not sure.
