Thanks for your feedback. Fdroid lags behind, the issue with off-by-one has been fixed. The light path show you that you missed (didn’t touch a single brick), this will reset your combo and limit the number of upgrades you get (+1 upgrade and choice if you never do it in a level). Have you extended the runs with the +1 level perk up to 3 times ? I’m trying to make the runs short, because I like playing while tests run or for a short break, ideally 5-10min.
Edit : i’ve replaced the light path that was really missunderstood by a big red “miss” text. You can try the latest version on itch or https://breakout.lecaro.me/ .
