Awesome game, thank you so much! Spent hours trying to beat it.
For those struggling, here is my build
My build was: Flamethrower weapon + Diamond character + Splinter upgrade
Flamethrower + Splinter is much more effective late game (2:00) than other weapons, because Flamethrower does area of attack, travels slower, and has a timer, which distributes the splinter spread more, making the chain reaction less likely to go out.
The fire heal upgrade (or whatever it is called) heals you in 15-30 seconds, but you need a high HP character to take advantage of that. I was offered fire heal only after the boss fight area disappeared, so I needed the extra HP to get through the boss fight. I then healed
Early game with flamethrower is weak, as it deals very little damage, and I was level 10 when I went into 5:00. However, you don’t actually need to shoot the flamethrower. I upgraded Movement Speed + Splinter + Lightning bug + Freeze, and focused on dodging.
The kills from the Lightning bug spawned flamethrower bullets which did the main killing, later it counted towards the fire healing.
You could say I got lucky with the upgrades. (PS: the last 6 upgrades were made after 2:00 when Splinter was doing all the work.)
