Thanks for the detailed feedback, and for playing both. That is exactly what I wanted: the wave where it ended and what ended it. Noted on the grenade launcher, it is the first thing I want to soften.
One heads up from my side: the counter on my games still shows 0 ratings, so the two 5 star ratings you left may not have saved. Itch sometimes wants the save pressed again in the ratings box. It matters a lot for visibility, so it is worth a second look.
I am going to Super Soccer now, on the phone in landscape as you suggested. I will come back with notes on the UI and how the controls feel on a mobile browser, and leave my rating. Thanks for the swap.
