Okay, this was way more fun than I expected, it was very satisfying to blast the asteroids with the hammers! I feel like it could develop into a full game if you want to!
Since you wanted some feedback:
- It feels like you stop progressing very early on and have nothing to look forward to in terms of progression once you've purchased every weapon.
- I feel like the boosters should have been limited/or on cooldown as they can be spammed infinitely.
- Upgrading the placed weapons might have been interesting, for example increasing hammer range, auto target for missiles, faster destroy time for laser and so on.
But these are all problems resulting from me wanting to have more of the game, so amazing job!
