Art Contest Results - Heal Snail Upgrades

Many moons ago, the Discord server began a lengthy discussion about possible ideas for Heal Snail's elixir forms. This is why an Art Contest happened, so that Frosty & Hollow snails are fully designed by the community! (Next thing you know, Imma get pressured into making Hollow Mussel smh)

🔮 Hollow Snail

When a nearby turret dies, spawn explosive mines on all surrounding tiles that drain enemy health upon explosion

btw: Frosty Snail had a very fiery birth. A fire truck paid my place a visit on the day I made Frosty Snail. No kidding. Oh my word. I wish you could smell the house right now as I'm typing this.

Speedrun Mode!

Speedrun Mode is a new "challenge option" that gives you ways to speed up enemy spawns and get through levels super fast. (Enabling Speedrun Mode also makes the game harder, for this reason.) Each level comes with its own Steam Leaderboard for completion times! You can now compete with other players for the most efficient way of beating each level! Operation Octo is normally not speedrunnable, due to the enemy waves spawning on set timers. However, in Speedrun Mode, enemy spawns follow “The 50% Rule”:

  • When 50% of the current wave enemies’ HP has been taken, the next wave spawns immediately.

  • (This feature was suggested by TylazerMK, who speedruns PvZ)

To enable Speedrun Mode, go to the new “Gameplay” section of your settings, and scroll down:

(Note: In order to submit your scores, you must be playing on Steam, and have active internet connection!) Here is a guide on the intricacies of speedrunning OO. -------------------------------------------------------------------
