definitly looking forward to buying it when I can, but a little something that at least I think might be a good idea is a demo. I mean, this seems like it COULD be the kind of game that you buy and then end up not liking, plus also you wouldn't need to put much in said demo, probably a small chunk of the levels from the first world, just a little something I thought might be nice and may actually convice more people that "hey, I like this I'm gonna buy the real thing" or "hey, aparently I didn't like this and I'm glad I didn't waste my money on something I would've ended up not liking"
I hope you enjoy the game when you buy it! In the meantime, there's no demo on itch yet but there's a Download Demo button on the Steam store page https://store.steampowered.com/app/1571220/Chessplosion/
