Really fun game! I loved the controls, they felt really intuitive and tight right from the start. I've played a couple of other games this jam which had similar controls but none of them felt this good so great job on that. The power-ups were also a great idea. I loved the big ship one. My strategy was to save my teleports for the power-ups haha.
The one critique I have is that there doesn't seem to be much progression. The game loop was fun but I wish there was more to it. Maybe different asteroid types or attack patterns. Or maybe multiple levels where you have a different ship each level with a different power. This one has teleportation, maybe another one can have a shooting mechanic, another one can be bigger but slower, another one can have a "dash" mechanic, etc. There's a lot of potential here for deep gameplay and replay value.
You already have the tight controls down and fun gameplay down so that's most of the work done. Hope you keep working on the game and flesh it out. Would love to revisit this in the future and play more! Awesome work.
