Hello, I made a piano-type app, would definitely purchase Construct2 but the apk is running slow on Android (working fine in the web preview). I'm using Intel XDK to create the apk, I had a glimpse of errors on this forum but it worked fine. I have 15 separate keys with 15 sound files, 15 events (basic touch button for audio clip). I've experimented with limiting the app to 12 buttons--square images created from the sprite editor as buttons, and no background (no clear background either) and it still runs slow on the phone. Any idea what I'm doing wrong? would the paid version on Construct2 be able to export a cleaner apk file? Again, I'd purchase it now if I knew I could make a working app. Thanks!
