@antti-haavikko : Whoa!! You must have spent a lot of time playing my game and analysing it. :slight_smile:
I agree on the most of the issues you mentioned. It took 20+ hours to get the tetris mechanics work properly, so I didn't have enough time for level design, player controller adjustments or visual effects. Yeah, maybe it wasn't a good idea to prevent player from pushing blocks while standing on them, even if it's 'realistic'. I literally didn't have any time to think about the input settings, but probably you're right, for example [space] for jumping would've been nice. I think that WASD is either for left-handed people or for situations, when right hand is needed for more important things, but of course it would've been easy to add it as an option.
Thanks for your deep analysis, I really appreciate it!
