Thanks for playing! I'm glad you liked it!
I definitely could have made the upgrade system more obvious, it was a deliberate choice to have it be something you discover but I'm not sure it was the right choice.
I'm so glad you like the graphics I was worried it wouldn't look cohesive.
the main movement mechanics are rocket jumping (which ofc requires you to unlock explosives) and bunny hopping which is a bit niche. A dash or something additional is a great idea and if I were to iterate this game further id definitely add powerups or a skill tree to include it.
Thanks again for playing, and thanks for the review!
