If you're making a shmup-like game why would you make the player movement seem as if he's skating on ice? The player having full control over his ship is very much a part of shmup. It might work as a kind of harder/different type of difficulty, but I'm not too sold on it. I also would expect the dash to have some sort of invincibility as to not make it one-dimensional and have gameplay to work as a cornerstone of your game yet not to accommodate it(i.e don't include it just because you have to do it as it's a shmup). Best of luck on both on your main game and this so called distraction.
This was a distraction from my main game.
Ended up being a Shmup type of game but not really. Kill all the enemies and select an upgrade between waves, dont forget you can dash by holding direction keys and Z.
Arrows to move
X to shoot
Arrows+Z to dash out the way
Currently only has 4 upgrades and 2 enemies. This was supposed to be something else but turned into some weird shmup. in the odd chance that people like it, I will update with more upgrades and enemies.
