Tedious and generally a hassle to use, the UI is messy, some buttons are too small and I accidentally hit buttons next to it and I have to scroll up and down a lot. The ads glitch sometimes which causes me to lose my progress, and I can't even skip them. Also, you have to use an in-game currency to buy different piece designs, more customization being locked behind a paywall just defeats the purpose. Go download ChessCraft instead, it's more limited but higher quality.

Y'all this is a genuinely wonderful concept for an app, but it straight up doesn't work. It's quite a chore to try using it to create a chess variant, but once you successfully create your game and watch your confirmation ad (or else lose all of the work you just did) you can get into a game, and it doesn't work at all. I mean it's actually really cool that you got the chess ai to work with the variants, but the pieces duplicate or break constantly, and the graphics fail to update frequently.

Adding new moves in editor is hard. Since when is negative vertical axis up? Edited move should always go on top or view its visual in some other way. Visual when editting moves should zoom back in after zooming out ridiculously. Maybe that zoom could be configurable? And themes? They don't do anything with the board? The board that is hard to read with half of the colors? Also not a big fan of ad monthly extortion. One-time ad removal would be nice.
