Short answer: Megabonk and Vampire Survivors are downloadable games. If you want the same "move, auto-attack, pick upgrades, survive the timer" loop instantly in a browser tab — including on a phone — play Mutlings. It adds one twist: your monster evolves into a different creature depending on what it eats.
▶ Play Mutlings freeWhat people like about this genre
- One-stick controls. You only move; weapons fire on their own.
- Build-crafting. Every level-up offers a few upgrades, and combinations snowball.
- Short, replayable runs with a clear goal: survive the clock, beat the boss.
Megabonk is known for a 3D low-poly look and big, chaotic builds; Vampire Survivors popularised the 2D "bullet heaven" format. Both are excellent but need a download and a purchase on PC or console.

Why try Mutlings
- Eat. Mutate. Survive. Bugs drop coloured nutrients — bugs, flowers, light, moss. Eat more of one colour and your Mochi becomes Chompo instead of Lumo.
- Tiny scale, big boss. You're thumb-sized in a backyard at night; the 5:00 boss is a Midnight Mower.
- Collection shelf. Every form you finish with goes into a glowing jar. Rare Glitch variants appear 1 in 64 evolutions.
- Daily Mutation and a share card for every run.
