I’ve made a lot of changes, gameplay is still pretty much the same, I plan to add another way to kill enemies during the week.

New features:

Nested enemies - Triangles have 1 hp, squares have 2 and so on.
Waves system - Enemies now come in waves, you can only access the shop at the end of each wave.
Shield Cooldown indicator - New cooldown bar for the shield, also the shield fades so you know when it’s running out.
No more instant-death - Enemies cannot spawn on top of you anymore.

Coming soon:

New weapon
SFX and BGM
Max HP increase in the shop
