Aesthetically and visually, Funtasia oozes a unique style and this solely carries the game - because the gameplay doesn't.

Genre wise it's a hill climb game akin to Earn to Die, but with a very shallow experience. You move right, while a progress bar diminishes as you move. Irrespective of whether you do it fast, or slow, it just does - basically a timer disguised as fuel/battery. There are no attacks, just the occasional jump.

Each level sees you drive a unique vehicle that handles slightly differently, and vehicle upgrades mainly help you get across the terrain faster/easier so that you can get to the next battery in time. However, vehicle progression and unlocks are tied to the one used for that level and boss. New level? You'll have to grind unlocks on a new car from scratch. And no, you can't use different cars on different levels, because that'd be too convenient.

End of level boss mechanics, while great and varied initially, repeat and overstay their welcome. Bosses include one hit kill mechanics that force a restart. Main issue is that each restart is unpredictable due to boss attack patterns, shoddy terrain, random hit registration and overall poor vehicle control.
Easily fixed if you had a health bar to take a couple of hits and bosses lasted longer to compensate for that, alas that's not the case.

Music wise, there are enough up beat and funky tracks that randomly cycle on each restart to keep things entertaining that match the overall aesthetic.

Unfortunately, the game hasn't been patched since it left Early Access in 2022, and achievements haven't worked since then either. I'd try it for free, otherwise there isn't enough here (besides the art-style) to warrant playing.
