itch.io

I’ve never really got into platformers, but this is really a pleasant, short, sweet experience. Smooth movements, varied aesthetics & challenges, good music, just pure fun hopping around collecting stars. A joy to play. Though, I feel like the scary big stars at the first levels don’t really fit with the rest of the game, but if it wasn’t for that then I wouldn’t have been here (came from the PSX demo disc!)

Judging from the file structure, I’m confident it’s Unity.

Yes, the Steam release is exactly the same as the itch.io one, with the exception that you can also have trading cards, which can compensate the game's price a bit. And thanks, I'm glad you have interests in the game!

The game itself is 32-bit and only requires a very old OS (Windows XP SP2) or higher. Did you download the game through the itch.io app?

Windows 7 Ultimate should be way more than enough to run the game.
