Hmm. The last part of my post got changed. I was trying to say Left Arrow, Up Arrow, and Right Arrow, but when I typed "" (Less Than, Carat, Greater Than), they disappeared. Perhaps it thought I was using an HTML tag.
Fun little game. I wish there was more.
Suggestion: Use a "Dual D-Pad" control setup like on the Fireboy and Watergirl games. Red is moved with AWD and Blue is moved with .
Suggestion: To make large numbers easier to read, write them using powers of 1000. For example, 45389 would be "45.3 K", 841035273 would be "841 M", 9164820354 would be "9.16 B", and 18264205749205 would be "18.2 T".
Sadly, this game is not colorblind-friendly. In World 1, the +, -, x, and / symbols are the color of the tiles that made them, but there's no way to tell them apart aside from color. In World 2, the tiles are all the same shape. You don't hit a colorblind-friendly area until World 3.
My suggestion: Add "visual texturing". For example, yellow symbols have dots, blue have horizontal lines, green have diagonal lines, and red have crosshatching.
I couldn't buy "Better Designs" despite having all the resources (45K Joy, 350 Planks, 500 Blocks, and 35 Metal). Maybe I only had 34.6 Metal. Suggestion: Instead of an Atelier increasing the output (how do I get 1.2 of an item, anyway?), keep the output the same and decrease the cost. Also, it would be nice if there were a way to increase Ore production independently of Stone production (maybe call it "Improved Smelters").
Another suggestion: Change (or give the player the option to change) the Next Upgrade text so that it shows what changes. For example, instead of "Production per minute: 5 Stone, 2 Tech. Next Upgrade: Production per minute: 5 Stone, 4 Tech", it could show "Production per minute: 5 Stone, 2 Tech. Next Upgrade: Production per minute: +2 Tech".
I have a suggestion. Please add icon(s) to the center of each space to show what resource(s) it produces. This should make it easier to look at a group and see that "OK, if I upgrade this building, it'll boost Tech production, but there's only one adjacent building that produces Tech. I'd be better off upgrading this other building, because it'll boost Wood production and has three Wood-producers next to it".
