I did day 3 with Lvl1 upgrades but you need to retry it several times until the bots are easier to beat.

Anyway, I've already upgraded 'till Lvl3 at day 4 (already completed) because it becomes too boring too many retries, upgrades are not too expensive and most probably it will be impossible to finish day 7 without this upgrades.
