Got to wave 23 on seconds try. By the end I was mainly fixing turrets, cause it felt too risky to go outside, also turrets had way better gear, cause my character mainly had upgrades that gave extra money at the end of the round.
It's hard to get a good build, cause a lot of upgrades are completely pointless without other ones, but they're not sold together, so while you wait for them to become available, you just get basic boring upgrades, such as extra damage and knockback.
Enemy hp pool growing from wave to wave feels unfair, cause in my opinion, a weapon that was good against them before, should stay good, if you want to force player to upgrade, IMHO you should introduce new enemies, that are visually distinct from old ones, even if they operate using the same logic as old ones.
Found several issues:
- When you try to drag an upgrade from one turret to another, its slot disappears.
- After some wave one turret's slots were completely gone. They were there before the wave, but were gone after. It still worked, but I couldn't upgrade it at all.
- Turrets block your shots, but don't block enemy shots, it's very unfair.
Other than that... it's ok.
