About Tideholm

Tideholm is a free lane tower defense game you play in the browser. It is made by greg, an independent developer, together with AI-assisted tools for code, art and sound. Everything in the game (art, sound effects and music) is made for Tideholm in code; the fonts are Nunito and Fraunces (SIL Open Font License 1.1).

The game

• 15 levels in two chapters (Holm Beach and the Storm Coast) with three bosses, plus an endless Free mode with a local leaderboard.
• 15 defenders, each with 5 levels; every level changes the look and adds an ability.
• The tide floods the front rows on some waves, which changes what works where.
• Co-op for two players on two devices (room code or QR code).
• Plain HTML5 Canvas and JavaScript, under 1 MB, no engine and no download. Graphics and sound are made in code. QR codes: Nayuki QR Code generator (MIT). Fonts: Nunito and Fraunces (SIL Open Font License).

How the game is funded

Tideholm is free. On this website it may show an ad between levels (never during a battle, never more than every few minutes) and offers an optional "watch an ad for bonus pearls" button. There are no purchases. See the privacy policy for what this means for your data.
